PELANDER, opinion of the Court.
¶ 1 Under A.R.S. § 28-8424(A)(3), a nonprofit corporation that leases airport property from a county “[pjerforms an essential governmental function as an agency or instrumentality” of the county. We here address whether, based solely on that statutory language, the Yuma County Airport Authority (“YCAA”) is an agent of Yuma County, making the County liable as principal for YCAA’s alleged breach of its sublease with Plaintiffs (collectively “DBT Yuma”). We hold that § 28-8424(A)(3) by itself does not make YCAA the County’s agent for purposes of imputed liability.
I.
¶ 2 In 1965, five persons formed YCAA as a nonprofit corporation to operate the Yuma International Airport under a lease from the County. That arrangement has continued for about fifty years. In 2008 and 2009, DBT Yuma subleased property at the airport from YCAA and operated a fixed base operation there as Lux Air. After YCAA evicted DBT Yuma and entered into a new sublease with another tenant, DBT Yuma sued YCAA for breaching its sublease and the implied covenant of good faith and fair dealing.
¶ 3 DBT Yuma later added Yuma County as a defendant, alleging that YCAA was the County’s “political subdivision” and “instrumentality and alter ego,” making the County liable for YCAA’s breach. The County and DBT Yuma each moved for summary judgment, and the trial court granted the County’s motion under Arizona Rules of Civil Procedure 54(b) and 56.
¶ 4 The court of appeals affirmed, holding that YCAA was not the County’s alter ego and that “A.R.S. § 28-8424 does not impose vicarious liability on counties for the activities of airport operators that are nonprofit corporate lessees of county airport land.” DBT Yuma, L.L.C. v. Yuma Cty. Airport Auth.,
¶ 5 We granted review because the interpretation of § 28-8424 is a legal issue of first impression and statewide importance. We have jurisdiction under article 6, section 5(3) of the Arizona Constitution and A.R.S. § 12-120.24.
II.
¶ 6 Although DBT Yuma’s liability theory against the County has morphed over time, DBT Yuma acknowledged before this Court that its claim against the County rests solely on § 28-8424. We accordingly focus on the statutory scheme and do not address whether a principal-agent relationship could exist between a governmental entity and its authorized airport authority because of an alter-ego relationship or other common law doctrines.
A.
¶ 7 Yuma County’s lease of airport property to YCAA was authorized by and executed pursuant to A.R.S. §§ 28-8411 and -8423. Under A.R.S. § 28-8424(A)(l), a nonprofit corporation/lessee such as YCAA is a “body politic and corporate.” That subsection also identifies the corporation’s public function— “exercising its powers for the benefit of the people, for the improvement of the people’s health and welfare and for the increase of the people’s traffic and prosperity.” A.R.S. § 28-8424(A)(l).
¶ 8 Courts in other states have determined that a “body politic and corporate” entity serving a public function is a public corporation. See, e.g., Rouse v. Theda Clark Med. Ctr., Inc.,
¶ 9 Despite the “body politic and corporate” language in § 28-8424(A)(l), DBT Yuma asserts that an airport authority is necessarily an agent of the authorizing governmental entity because the airport authority “[pjerforms an essential governmental function as an agency or instrumentality of the city, town, county or state.” A.R.S. § 28-8424(A)(3) (emphasis added). The terms “agency” and “instrumentality” are not defined in A.R.S. §§ 1-215, 28-101, or elsewhere in Title 28. Absent statutory definitions, courts generally give words their ordinary meaning, State v. Cox, 217 Ariz. 353, 356 ¶ 20,
¶ 10 In the public law context, however, the phrase “agency or instrumentality” is a term of art, for which dictionary definitions are not helpful in determining its meaning. We do not view statutory words in isolation, but rather draw their meaning from the context in which they are used. See Adams v. Comm’n on Appellate Court Appointments, 227 Ariz. 128, 135 ¶34,
¶ 11 Our conclusion is buttressed by viewing both state and federal legislation more broadly. Many statutes, like § 28-8424, authorize the creation of a nonprofit corporation that is expressly made an “agency or instrumentality” of the government. See, e.g., 12 U.S.C. § 1452 (creating the Federal Home Loan Mortgage Corporation as a “body corporate” and a federal agency); see also 28 U.S.C. § 1603(b) (defining an “agency or instrumentality of a foreign state”), 42 U.S.C. § 1437a(b)(6) (defining “public housing agency” as “any State, county, municipality, or other governmental entity or public body (or agency or instrumentality thereof)”); A.R.S. § 36-1401(2) (defining “public housing authority” as “an agency of a city, town or county created and controlled pursuant to this article”); cf. A.R.S. § 30-102(B) (creating the Arizona power authority as a “body corporate and politic”). Such statutes authorize the creation of a separate juridical entity with powers to sue and be sued, own or lease property, enter contracts, and conduct other specified activities.
¶ 12 In addition, the designation as an “agency or instrumentality” often has consequences for sovereign immunity, inter-governmental tax immunity, or foreign sovereign immunity. See, e.g., First Nat’l City Bank v. Banco Para El Comercio Exterior,
¶ 13 Consistent with these observations, other courts have held that statutes describing an entity as an “agency and instrumentality” of a governmental body do not, by themselves, make the government liable based on a statutory principal-agent relationship. See Ciulla v. State,
¶ 14 Our view also finds support in the Restatement, which distinguishes common-law requirements for “agency” (which DBT Yuma acknowledges are not met here) from statutory terms such as those contained in § 28-8424(A)(3). See Restatement (Second) of Agency § 1 cmt. f (Am. Law Inst.1958) (“Whether the word ‘agent’ as used in a statute corresponds to the meaning here given depends, with other factors, upon the purpose of the statute.”); Restatement (Third) of Agency § 1.01 cmt. b (Am. Law Inst.2006) (“More generally, legal usage varies. Some statutes and many cases use agency terminology when the underlying relationship falls outside the common-law definition.”).
C.
¶ 15 The Arizona cases on which DBT Yuma relies are inapposite. In Hertz Drive-Ur-Self System, Inc. v. Tucson Airport Auth.,
¶ 16 DBT Yuma’s reliance on two decisions by the court of appeals likewise is misplaced. See Thompson v. Tucson Airport Auth., Inc.,
¶ 17 Like Hertz, those cases neither addressed § 28-8424 nor held that a nonprofit airport authority has a principal-agent relationship with its authorizing governmental entity. They do not support DBT Yuma’s broad contention that YCAA is the County’s agent merely because it manages the airport.
D.
¶ 18 Finally, DBT Yuma’s reliance on A.R.S. § 28-8428 also is misplaced. That
¶ 19 As noted above, however, a nonprofit/lessee airport authority operating an airport is a “body politic and corporate,” § 28-8424(A)(1), and as such is generally not deemed an agent of the county. See supra, ¶ 8. To instead conclude, based solely on § 28-8428, that an airport authority is an agent of the county for purposes of imputing the former’s liability to the latter would flatly contradict § 28-8424(A)(l), rendering that subsection superfluous. See Lemons v. Superior Court,
III.
¶ 20 For the foregoing reasons, we affirm the trial court’s summary judgment in favor of Yuma County. Although we agree with the result reached by the court of appeals, we vacate paragraphs 11 through 19 of its opinion.
