twój

Twój is a Polish possessive determiner meaning "your" used to indicate ownership by the person being addressed in the singular, informal form of the second person (ty). It accompanies a noun and must agree with that noun in gender, number, and case.

Forms and usage: In the singular, the form changes with the noun’s gender: twój (masculine), twoja (feminine), twoje (neuter). For example: twój dom, twoja mama, twoje auto. When addressing more than one person, the possessive has a different set of forms: wasi (masculine personal plurals), wasza (feminine singular or plural), and wasze (neuter singular or feminine/neuter plural). Examples: Wasi koledzy przyszli. Wasze dzieci są w domu. Twoje dzieci są w domu. The choice between "twój" and "wasz" mirrors whether you are speaking to one person or to multiple people.

Usage notes: Twój is the informal second-person possessive. In formal address, Polish often uses a different family of forms built from pan/pani (for example pański/pańska/pańskie) or other polite constructions, rather than extending twój to a formal you. Like other Polish possessive adjectives, twój declines like an adjective and must agree with the noun it modifies.

Etymology: Twój comes from the old Polish possessive construction and is cognate with similar forms in other Slavic languages (for example Russian tvoy, Ukrainian tvoy, Czech tvůj).
