felületükön
Felületükön is a Hungarian word. It is the locative plural form of the word "felület," which translates to "surface" in English. Therefore, "felületükön" means "on their surface" or "upon their surfaces." This grammatical construction indicates a location or position that is upon the exterior of multiple objects. The suffix "-ükön" is a possessive suffix in the third person plural ("their") combined with the "-ön" locative suffix ("on"). This word would be used in sentences where the speaker is referring to something being situated on the exterior of more than one item. For instance, one might say that "a festék felületükön száradt" which translates to "the paint dried on their surface." The context of the sentence would clarify what "their" refers to. The word emphasizes the exterior aspect and the multiplicity of the objects involved.
