Opinion by
¶ 1 Plaintiff, -Michele Fry, appeals the district court’s judgment dismissing her complaint, which alleged defamation and related claims against defendants, Kurtis Lee and The Denver Post, LLC (the Post), pursuant
I. Procedural History and Background
¶ 2 In 2011, Fry ran as a candidate for the District 5 seat on the Denver City Council. As part of her campaign, Fry responded to a questionnaire that the Downtown Denver Partnership (DDP) provided to the District 5 candidates. The candidates’ responses were made public.
¶ 3 In March 2011, Lee, a reporter for the Post, contacted Fry by telephone regarding one of her answers on the DDP questionnaire, which appeared to have been copied verbatim from an on-line publication authored by the National League of Cities (NLC). During that phone convei’sation, Fry denied that she had copied any text without attribution in her responses to the DDP questionnaire. Immediately afterward, Lee sent Fry an e-mail in which he presented, side-by-side, Fry’s questionnaire answer and the text from the NLC publication. They were identical.
¶ 4 As relevant here, Fry responded to Lee’s e-mail as follows:
Thanks for sending and pointing this out. I now see what you mean and it’s my fault. I’ve read hundreds of pages while preparing to run for city council. I inadvertently used information in a National League of Cities research document while preparing my own position papers.
I would never intentionally lift from another source and should have been more careful.
I regret not having cited the NLC, and for that I apologize. I have called ... onp of the authors of the document; I apologized to her directly.... I have now made the appropriate citation in the DDP questionnaire.
¶ 5 That same day, Lee -wrote, and the Post published, an article regarding his interaction with Fry. The article’s headline stated, “Denver city council candidate caught up in plagiarism charge.” The body of the article reported, as pertinent here,
Michele Fry ... plagiarized answers on a candidate questionnaire....
In outlining what she would do to foster economic activity and employment, over half of Fry’s response was ripped verbatim from a National League of Cities Economic Development pamphlet....
On a separate question ... Fry’s entire response was lifted from the National League of Cities pamphlet.
When first contacted by The Denver Post, Fry denied ever plagiarizing her response to the questionnaire.
“I do research, I’m just now finishing my MBA at Regis Jesuit,” said Fry. “I’m not dumb. I would never plagiarize anything.” However, after seeing a side-by-side comparison that showed her responses were not her original work, and did not cite the proper source, she recanted.
“I would never intentionally lift from another source and should have been more careful,” said Fry. “I’ve definitely learned something about research and the scrutiny of political races and will work even harder.”
¶ 6 The next day, the Post republished a substantially similar version of the article on its website, with the new headline, “Denver council candidate plagiarized answers on questionnaire.” The body of the article was essentially the same as. the original article, except for one additional sentence explaining that the DDP had allowed Fry to attribute her answers to the NLC after the Post had pointed out the “discrepancy.”
¶ 7 Subsequently, Fry wrote a letter to the Post’s editor challenging the accuracy of the articles and claiming that they “grossly misrepresented the situation.” The Sunday editor of the Post responded to Fry by letter, articulating the Post’s position that the articles accurately reflected what had transpired. The Post refused to publish a correction to the articles.
¶ 8 Fry then filed this action against Lee and the Post. In her First Amended Complaint (amended complaint), she alleged seven claims for relief, including defamation per se, defamation per quod, respondeat superi- or, negligence, negligence per se, intentional infliction of emotional distress, and deceptive trade practices. All the claims were prem-
¶ 9 In the amended complaint, Fry alleged facts regarding her exchanges with Lee, NLC, and DDP, as well the particulars of the Post’s articles. She then alleged that defendants had “knowingly or with reckless disregard for its truth or falsity published the false statement that Ms. Fry had been ‘caught up in [a] plagiarism charge,’ ” as well as “false and misrepresentative statements that misled people to believe that [she] had admitted to intentionally or deceitfully failing to cite the NLC.” The thrust of her amended complaint was that the Post’s use of the words “plagiarize,” “charge,” “caught up,” and “recant” had falsely communicated that Fry (1) had intentionally copied the NLC text, (2) had been formally charged with the commission of a crime for doing so, and (3) had admitted to intentionally copying the NLC text. She further asserted that the alleged defamatory statements had caused her reputational, economic, and noneconomic damages “similar to what she would have suffered had she actually committed a crime or been arrested, indicted, or convicted.”
¶ 10 Fry also alleged that the on-line version of the Merriam Webster Third New International Dictionary defined the word “charge” as “a formal assertion of illegality” or “a statement of complaint or hostile criticism,” and defined the phrase “caught up” as “to bring about arrest for illicit activities.” With respect to the word “plagiarize,” she alleged, “At least a substantial and respectable minority of The Post’s millions of readers interpret ‘plagiarism’ as describing an act of intentionally or deceitfully passing off another’s writings or ideas as one’s own.” However, Fry did not refer to any dictionary definition of the word “plagiarize” in the amended complaint.
¶ 11 Fry also attached various exhibits to her amended complaint, including, as relevant here, print-outs of the Post’s articles, her e-mail response to Lee’s inquiry, and the Sunday editor’s letter to her explaining the Post’s position that the articles were “factual, unembellished accounts of [Fry’s] response to the questionnaire, and [her] acknowledgement that it was copied from previously published work of others without attribution— the definition of plagiarism.”
¶ 12 Defendants filed a motion to dismiss Fry’s amended complaint pursuant to C.R.C.P, 12(b)(5) on the ground that the challenged statements were substantially true, and thus not actionable, under the heightened standard of review applicable to defamation claims implicating constitutional rights under the First Amendment. Fry timely filed a response to the motion, and defendants filed a joint reply.
¶ 13 In July 2012, the district court issued an order dismissing the amended complaint “in its entirety with prejudice.” In its order, the district court acknowledged that “[i]n cases involving freedom of the press, this Court has a special burden of preliminarily testing the validity of the complaint to ensure that the case will not constitute a forbidden intrusion on free speech liberties.”
¶ 14 In dismissing Fry’s defamation claims, the district court ruled as follows:
Plaintiff disputes the meaning of the words “charged,” “plagiarism,” and “recant,” and claims that the articles would make it appear to the ordinary person that she had been formally “charged” with the “crime” of “plagiarism.” It is undisputed that there is no such crime as plagiarism. A reasonable person simply could not come to that conclusion. See Knapp v. Post Printing & Publ’g Co.,111 Colo. 492 , 498-99,144 P.2d 981 , 984 (Colo.1943) (“[a] newspaper publication must be measured by its natural and probable effect upon the mind of the average lay reader”).
Furthermore, the substance of the articles is true. The dictionary definitions of the challenged words support the Defendants’ description of events. “Charge” typically means “accusation.” Webster’s Dictionary New Edition 83. “Plagiarism” means “to present the ideas or words of another as one’s own,” Merriam Webster Dictionary 378 (2005). Furthermore, no reasonable person would understand “plagiarism” to necessarily mean that Plaintiff intentionally stole another’s words. “Recant” means to “make an open confession of error.”*848 Merriam Webster Dictionary New Edition 414 (2005). It is undisputed that Plaintiff was accused of presenting the words of NLC as her own, and that she later confessed her error. The average lay reader would understand these words to mean exactly that.
¶ 15 The district court further found that the articles were not rendered false simply because they omitted .the facts that Fry “called and apologized to the NLC and received [its] blessing to use the quote with citation.” It also dismissed Fry’s other claims on the ground that they were “all predicated on these articles and on the same facts that give rise to her defamation claims.”
¶ 16 This appeal followed.
II. Standard of Review and Applicable Law
¶ 17 We review a district court’s decision to grant a C.R.C.P. 12(b)(5) motion to dismiss de novo and apply the same standards as the district court. Denver Post Corp. v. Ritter,
¶18 A C.R.C.P. 12(b)(5) motion is looked upon with disfavor, and a complaint should not be dismissed .unless it appears beyond a doubt that a claimant can prove no set of facts in support- of his or her claim which would entitle him or her to relief. Pub. Serv. Co. v. Van Wyk,
¶ 19 When considering a motion to dismiss for failure to state a claim, we may consider only the facts alleged in the pleadings, documents attached as exhibits or incorporated by reference, and matters proper for judicial notice. Denver Post Corp.,
¶ 20 A claim for defamation requires, at a minimum, the publication of a false statement of a defamatory nature. Burns v. McGraw-Hill Broad. Co.,
¶ 21 Where, as here, a defamation claim involves' a public figure or a matter of public concern, it triggers certain constitutional privileges. Smiley’s Too, Inc. v. Denver Post Corp.,
¶ 22 Substantial truth is an absolute defense to a defamation claim. Gomba v. McLaughlin,
¶ 23 In determining whether a challenged statement is substantially true, the inquiry should focus on how an average reader would read the statement. Miles,
¶ 24 Finally, because the threat of protracted litigation could have a chilling effect on the constitutionally protected right of free speech, prompt resolution of defamation actions, by summary judgment or motion to dismiss, is appropriate. Barnett,
III. Analysis
¶25 Fry contends that the district court erred when it granted defendants’ motion to dismiss because (1)' the court misapplied the standard of review for a C.R.C.P. 12(b)(6) motion; (2) reasonable people- could have found that the challenged statements were capable of bearing defamatory meaning and were materially false; and (3) the court improperly summarily dismissed Fry’s ancillary claims based on the failure of her defamation claims.
¶ 26 We disagree for the reasons discussed below.
A. Application of the C.R.C.P. ■. 12(b)(5) ■ Standard of Review
¶ 27 Fry contends that, in ruling on the C.R.C.P. 12(b)(6) motion, the district court erred because it did not accept her pleaded facts as true and construe them in the light most favorable to. her, as required under the applicable standard, of review. Specifically, she contends that the district court erred when it improperly considered facts and documentary materials provided by defendants and when it consulted and relied on dictionary definitions regarding the meaning of the words “charge,” “plagiarism,” and “recant.”
¶ 28 We perceive no error in, the district court’s application of the C.R.C.P. 12(b)(6) standard of review. .Nowhere in its order did the district court make reference to or rely on any documentary materials attached to defendants’ motion to dismiss other than documents referenced in or attached to the amended complaint itself. Rather, the district court cited the proper legal standard for its review, noting that it “may consider only the facts alleged in the pleadings, documents attached as exhibits or incorporated by reference in the pleadings, and matters of which the court may take judicial notice.” See Denver Post Corp.,
¶29 Fry argues that the district court erred by relying on standard dictionary definitions and was .required, instead, to accept as true the definitions that she purported to aver as facts in her amended complaint. We are not persuaded. In ruling on a C.R.C.P. 12(b)(5) motion tó dismiss, the meaning of allegedly defamatory words is a matter of. law left to the court — not a factual allegation to which it must defer. See Knapp,
¶ 30 Rather, in making its determination, the district court properly relied on the plain and ordinary meanings of the allegedly defamatory words. See Anderson,
¶31 Therefore, contrary to Fry’s contention, the district court was not required to accept the meanings alleged in her amended complaint as factual matters; instead, it properly referred to lay dictionaries to determine, as a matter of law, the ordinary and plain meanings ascribed to the challenged words.
B. Defamatory Meaning and Substantial Truth
¶ 32 Fry next contends that the district court erred because, if all her factual aver-ments aré taken as true and construed in the light most favorable to her, the amended complaint adequately stated a claim that the challenged words and phrases were defamatory and materially false, and furthermore, that defendants intended this effect. We disagree. •
¶ 33 The district court concluded that “all of Fry’s defamation claims must be dismissed” on two grounds: (1) that the words “charged,” “plagiarism,” and “recant” would not be interpreted by a reasonable person to have the defamatory meanings Fry alleged in her amended complaint and (2) that “the substance of the articles is true.” The district court’s analysis of the meaning of the challenged words is necessarily intertwined with its analysis of the substantial truth of the published statements. See Bustos v. A & E Television Networks,
i. Meaning of the Challenged Words
¶34 We first consider whether the trial court erred in the meanings it ascribed to the challenged words and phrases. With respect to Fry’s contention that the court was required to accept as true the definitions she provided in her amended complaint, as already noted, we are not persuaded. See Knapp,
¶ 35 With regard to the use of the word “plagiarism,” the district court found that, according to the Merriam Webster Dictionary, “plagiarism” means “to present the ideas or words of another as one’s own,” without any reference to intent. Merriam Webster Dictionary 378 (2005).
¶ 36 The parties have not cited, and- we have not found, any Colorado appellate cases defining the word “plagiarize.” However, other courts have indicated, consistently with the standard dictionary definitions, that plagiarism does not necessarily or even typically entail the concept of intent. For example, the United States Supreme Court has defined plagiarism as “the use of otherwise unprotected works and inventions without attribution,” without any reference to intent. Dastar Corp. v. Twentieth Century Fox Film Corp.,
¶37 Similarly, other courts have defined plagiarism, as used in the academic context, as did the district court here. See Newman v. Burgin,
¶ 38 Both articles published .by the Post explicitly quoted Fry’s statement that she did not intentionally copy the NLC text, and nothing in those articles expressly ór inferentially suggested anything to the contrary. See Burns,
1F39 Next, we consider the phrase, “caught up in plagiarism charge.” Fry alleged in her amended complaint that “almost all people interpret the use of the verb phrase ‘caught up’ and the noun ‘charge’ in the same clause to impute the commission of a crime.” Again, given that it is a matter of law for the court to decide whether a phrase has defamatory meaning, the district court was not required to accept her allegation as fact. See Denver Post Corp., 255 P.3d at
¶ 40 The district court’s conclusion is further supported by the articles as a whole, which make no mention whatsoever of any criminal charge or law enforcement entities. Rather, the articles use the word “charge” squarely in the context of an accusation made against Fiy by the Post. Indeed, Fry concedes in her amended complaint that a reader would not infer that the challenged phrase implied criminal charges “if the context of the publication makes it clear that a different meaning was intended.” In our view, the published articles did just that.
¶ 41 Case law also supports the definition of “charge” relied on by the district court. For example, United States Supreme Court defamation and libel cases consistently use 'the word “charge” in reference to noncriminal accusations made by the press. See Herbert v. Lando,
¶ 42 Colorado cases have also used the word “charge” in the same manner — as referring to noncriminal accusations made by the press. See Diversified Mgmt., Inc.,
¶ 43 Fry’s reference in her briefs on appeal to the definition of “charge” found in Black’s Law Dictionary does not persuade
¶ 44 Nor are we persuaded by Fry’s argument that defendants’ use of the words “caught up” in the first article’s headline implied criminal conduct by Fry. In the amended complaint, Fry relied on the online version of the Merriam Webster Third New International Dictionary as defining “caught up” to mean “to bring about arrest for illicit activities.” However, that source defines the phrase “caught up” as the past tense of the phrase “catch up.” Merriam Webster Dictionary, http:Hwma. merriam-web-ster. com/'dictionary/camghtüp. Further, the definition proffered by Fry is listed as only the fourth possible definition for the phrase, including, as1-relevant here, “1 b; ensnare, entangle < education has been caught up in a stultifying mythology ...” Id. Not only is Fry’s proffered definition listed ás a less common usage of the phrase, the explanatory sentence provided by the online dictionary in connection with that definition (“the police caught up with the thieves”) does not even correspond with defendants’ use of the phrase in the article’s headline.
¶ 45 Accordingly, we perceive no error in the district court’s conclusion that an average reader would not have inferred that Fry had been the subject of a formal criminal charge, but rather that she had been accused by defendants simply of copying the NLC’s text without attribution.
¶ 46 We also reject Fry’s arguments regarding defendants’ use of the word “recant.” Fry alleges in her amended complaint that the word “recant” implies that she admitted to intentionally presenting the copied text as her own. The district court concluded that, according to a standard dictionary definition, “recant” means to “make an open confession of error.” Merriam Webster Dictionary 414. Viewing the articles as a whole, and the use of the word “recanted” in context, we perceive no error in the district court’s conclusion that an average lay reader would have understood defendants’ use of “recant” to be consistent with this dictionary definition. Indeed, the articles made it abundantly clear that Fry’s position was that her plagiarism was unintentional. The clear import of the articles was that Fry recanted her original erroneous statement to Lee that she did not copy the NLC’s text. See Knapp,
¶ 47 To the extent that Fry challenges the phrase “ripped verbatim” for the first time in her reply brief on appeal, we decline to address her argument, because it was not raised either in the district court or in her opening brief on appeal. See Melat, Pressman & Higbie, L.L.P. v. Hannon Law Firm, L.L.C.,
¶ 48 In sum, we perceive no error in the district court’s overall conclusion that a reasonable or average lay reader would not have read the challenged statements with the defamatory meanings ascribed to them by Fry. See Knapp, 111 Colo, at 498-500,
2. Substantial Truth
¶49 We next consider the district court’s second ground for dismissing. Fry’s amended complaint — that the articles were substantially true. Again, we perceive no error and agree with the district court’s conclusion that Fry’s defamation claims are not actionable under the doctrine of substantial truth. Gomba,
¶ 50 To be actionable, an allegedly defamatory statement must contain a material falsehood. See Bustos,
¶ 51 The district court held that “the substance of the articles [was] true” because defendants’ description of the events was consistent with the plain and ordinary meanings of the challenged words “plagiarism,” “charge,” and “recant.” The district court observed:
It is undisputed that Plaintiff was accused of presenting the words of the NLC as her own, and that she later confessed her error. The average lay reader would understand these words to mean exactly that.
¶ 52 The district court further concluded that the impact of certain omitted facts did not require a different conclusion: ¡
Plaintiff argues that the articles should have included the fact that she called and apologized to the NLC and received [its] blessing to use the quote with citation. The Court finds that these additional facts would not have changed the tenor of the articles.
¶ 53 We perceive no error in the district court’s reasoning. The plain and ordinary meaning of the articles truthfully and accurately reflected the undisputed facts that (1) Fry copied significant portions of NLC text without attribution; (2) when questioned by Lee, she initially denied having done so; and (3) when confronted with the identical text, she then admitted she was in error and had indeed copied the text.
¶ 54 We agree with the district court that any version of the pertinent events that would have included the omitted facts referenced by Fry simply fails to produce a different effect than the version that was published. See TMJ Implants, Inc. v. Aetna, Inc.,
■ ¶ 55 While including the omitted facts of Fry’s apology to NLC and its response to her might have provided a more well-rounded picture of Fry’s actions after it was already established that she had copied the NLC’s text without attribution, these facts would not have changed the overall truthful gist of the article that she had indeed copied significant portions of NLC text without attribution; denied that she had done so;, and then, once confronted, changed her position and admitted that she had made a mistake. See also Masson,
Every news story ... reflects choices of what to leave out, as well as what to include.... Courts must be slow to intrude into the area of editorial judgment not only with respect to choices of words, but also with respect to inclusions in or*855 omissions from news stories. Accounts of past events are always selective, and under the First Amendment the decision of what to select must almost always be left to writers and editors. It is not the business of government.
NBC Subsidiary,
¶ 56 Fry’s assertion that at least some portion of the Post’s extensive readership was likely to have interpreted the articles in the defamatory maimer she alleges is simply immaterial to the appropriate legal analysis here.
¶ 57 Furthermore, the articles concerned Fry’s candidacy for public office. A candidate for public office
invites consideration of his qualifications, and tenders, as an issue to be tried out publicly before the people, his honesty, integrity, and fitness for the office to be filled.... It is one of the hazards which a candidate for public favor must face that he is exposed to critical, and perhaps unjust, comments, but these, unless they transcend the bounds of what the law permits, must be borne for the sake of maintaining a free press.
Knapp,111 Colo. at 500-01,
¶ 58 In sum, we perceive no error in the district courts judgment dismissing Fry’s defamation claims on the bases that the challenged statements were not subject to interpretation by a reasonable reader as being defamatory as she alleges, and that they were substantially true. See Barnett,
C. Ancillary Claims
¶ 59 Finally, Fry contends that the district court also erred when it dismissed her other claims for relief. Fry’s ancillary claims included respondeat superior, negligence, negligence per se, intentional infliction of emotional distress, and deceptive trade practices.
¶ 60 The district court dismissed these claims as follows:
Plaintiffs other claims must be dismissed as well. They are all predicated on these articles and on the same facts that give rise to her defamation claims. Alternative torts cannot be used to evade the constitutional requirements for defamation actions.
¶ 61 We perceive no error. Courts have employed similar reasoning to dismiss a variety of ancillary claims in defamation and libel cases. See Hustler Magazine, Inc. v. Falwell,
¶ 62 Accordingly, we conclude the district court did not err in dismissing Fry’s ancillary claims, given that they allege damages resulting from defendants’ purportedly defamatory statements. Absent a legally sufficient pleading of material falsity, recovery is barred by the First Amendment. See Williams v. Cont’l Airlines, Inc.,
IV. Attorney Fees
¶ 63 Defendants request an award of attorney fees on appeal pursuant to section 13-17-201, C.R.S. 2012. Because the district court properly dismissed Fry’s claim under C.R.C.P. 12(b)(5), we grant defendants’ request for attorney fees on appeal. See Walker v. Van Laningham,
¶ 64 We exercise our discretion under C.A.R. 39.5 and remand to the district court for a determination of the amount of reasonable attorney fees to be awarded to defendants for this appeal. Id.
¶65 The judgment is affirmed, and the case is remanded for further proceedings consistent with this opinion.
. Courts also typically rely on lay dictionaries to determine the ordinary meaning of challenged words in many other legal contexts as well. See Hecla Mining Co. v. N.H. Ins. Co.,
. In its order, the district court referred to the 2005 edition of the Merriam Webster Dictionary. We note that the print version of Webster’s Third New International Dictionary 1728 (2002) similarly includes two definitions of the word "plagiarize" that do not include intent as part of the definition — (a) to "use a created production without crediting the source”; and (b) to "present as new and original an idea or product derived from an existing source.”
. The print edition of Webster's Third New International Dictionary similarly defines "charge," in this context, as "an accusation of a wrong or offense”; or as "a statement of complaint or hostile criticism.” Webster's Third New International Dictionary 377.
. In her reply brief, Fry purports to quote from reader comments on the Denver Post website to show that three readers did indeed interpret the articles as defamatory. She argues that these comments were properly before the district court because they were available at a website address printed on a copy of the challenged article that was attached to her amended complaint. We are not persuaded that these comments were thereby properly before the district court and note that this is not the type of information of which a court can properly take judicial notice. See Castillo v. Koppes-Conway,
