¶ 1. Melanie Bauer, personally, and as personal representative of the estate of Matthew W Oleson, appeals from an order dismissing her complaint agаinst State Farm Mutual Automobile Insurance Company. The issue raised on summary judgment is whether the underinsured motorist (UIM) clause of her automobile policy with State Farm coverеd her son, Matthew Oleson, when he was killed while riding in an automobile driven by a friend. We conclude that Matthew did not "reside primarily with" Bauer and *483 therefore, under the unambiguous language of Bauer's policy, Matthew was not insured by Bauer's UIM coverage. We therefore affirm.
¶ 2. Summary judgment methodology is well known and we need not repeat it here. Our review is dе novo, and is limited to the pleadings, and the parties' affidavits and other material.
Nielsen v. Spencer,
¶ 3. Matthew lived with his mother from birth through high school. He then enlisted in the Navy, and attended bоot camp and advanced training from June through December 2001. He returned to his mother's home for three weeks' leave. He was then sent to his "home port" of Gulf Port, Mississippi, from where he was dispatched on several missions. For the first six months in Gulf Port, he lived on base. After that, he rented an apartment with a roommate. Between missions, when granted lеave, he would return to his mother's home for two weeks' time. Matthew obtained a Mississippi fishing license and kept his motorcycle and personal items at his apartment. He maintained a Wisconsin operator's permit and a Wisconsin bank account, to which his pay checks were deposited. His *484 motorcycle was licensed in Wiscоnsin. His income tax return listed his mother's home as his home address. His mother kept a room in her home for his use, and Matthew stored bows, guns and clothing there. He planned on returning to Wisconsin after his five-year Navy enlistment. He was killed in an automobile accident in Wisconsin on May 9, 2004, while riding with an underinsured driver.
¶ 4. Melanie Bauer's UIM clause in her policy with State Farm dеfines the persons insured by UIM vehicle coverage as: (1) the first person named in the declarations; (2) his or her spouse, and (3) their relatives. The policy's definition of a "rеlative" is "a person related to you or your spouse by blood, marriage or adoption who resides primarily with you. It includes your unmarried and unemancipated child аway at school." The parties' dispute concerns whether, for purposes of UIM coverage, Matthew "reside [d] primarily" with his mother, Melanie Bauer, at the time of his death.
¶ 5. Wisconsin cases have not interpreted the phrase "resides primarily with you." Bauer asserts that cases interpreting the word "resident" are relevant to our interрretation of this phrase. She relies on several of these cases, the first of which is
Doern v. Crawford,
¶ 6. Bauer asks us to apply the test for whether a person was a "resident of the same household" that the court employed in
Pamperin v. Milwaukee Mut. Ins. Co.,
[A] determination as to whether a person is a resident or member of a household in the present context is dependent upon three factors: (1) Living under the same roof; (2) in a close, intimate and informal relationship; and (3) where the intended duration is likely to be substantial, where it is consistent with the informality of the relationship, and from which it is reasоnable to conclude that the parties would consider the relationship in contracting about such matters as insurance or in their conduct in reliance thereon.
Id. (citation omitted).
¶ 7. We have the same difficulty with Pamperin that we had with Doern. We are not interpreting the policy language the court interpreted in Pamperin. Pamperin concluded that the jury's finding as to residency was not supported by the evidence. The Pamperin threе-factor test is: (1) Living under the same roof; (2) in a close, intimate and informal relationship; and (3) where the intended duration is likely to be *486 substantial. Matthew received two-weeks' lеave between assignments. His fatal accident occurred during one of those leaves. Even assuming that the accident occurred near the end of his leave, the time spent with Bauer, like the week to ten-day stay in Pamperin, was not substantial. Therefore, even if we used the Pamperin test, Bauer would not prevail.
¶ 8. Again assuming that the phrase "resident of the same household" has the same meaning as the phrase "resides primarily with you," Bauer argues that
Seichter v. McDonald,
¶ 9. There is another differеnce. The Bauer policy adds to the definition of "primarily resides with you" by including an additional category of insured persons. "[R]esides primarily with you.... includes your unmarried and unemancipated child away at school." Were it not for this sentence, unmarried and unemancipated children away from home at school would not be insured under their рarents' UIM coverage because they would be primarily residing in a college dormitory or apartment and not at home.
*487
¶ 10. Bauer asserts that the sentence in her рolicy extending coverage to students who do not primarily reside at a pertinent relative's home provides an
illustrative example
of situations where a person not primarily residing with a relative would still be an insured. We disagree. If the "student" sentence were an example only, there would be no need for the sentence in the first place. If, as Bauer argues, the test is not whether a person is living under a relative's roof, but whether some other sort of relationship has ended and the child has started a life without the relativе, each case would have to be litigated to see whether this test is fulfilled. As we recognized in
Seichter,
"previous decisions of this court indicate that no one factor is controlling on the question of household membership but that all of the elements must combine to a greater or lesser degree in order to establish the relationship."
Seichter,
¶ 11. The cases Bauer relies on do not interpret an insurance policy which includes the word "primarily" or "primary." The modifier "primarily" makes the phrase "resides primarily with you" unambiguоus, at least as applied to the facts of this case. Merriam Webster's Collegiate Dictionary 925 (10th ed. 1993) defines "primarily" as "for the most part," or "chiefly." One meaning it gives "рrimary" is "of first rank, importance or value," or "principal." Id. To have a "primary" residence under this commonly accepted definition means there can only bе one primary residence. Because one cannot "primarily reside" in more than one place, the use of the modifier "primarily" avoids the uncertainties that were a cause of the disputes in Doern, Pamperin, Seichter and Ross.
¶ 12. The material facts and reasonable inferences from these facts are undisputed. This case is *488 therefore apprоpriate for summary judgment disposition. Wis. Stat. § 802.08(2) (2003-04). We conclude that Matthew did not primarily reside with his mother at the time of his death. Accordingly, the UIM clause of Bauer's policy with State Farm did not provide coverage for Matthew. We affirm the trial court's order granting summary judgment to State Farm.
By the Court. — Order affirmed.
