tygodniach

Tygodniach is the locative plural form of the Polish noun tydzień, meaning weeks. It is used when the noun is governed by a preposition that requires the locative case, most commonly with the prepositions w (in) and o (about). In practice, tygodniach refers to weeks as a time period or as part of a discussion about weeks.

In usage, tygodniach appears in phrases that describe time spans or events occurring within weeks. For example: "W tygodniach, które minęły, wiele się zmieniło" (In the weeks that have passed, a lot has changed), and "O tygodniach nauki mówiono na konferencji" (There was talk about the weeks of study at the conference). The form helps situate information on a weekly scale rather than a specific day or a longer period.

Tygodniach contrasts with the genitive plural tygodni, which is used after numerals and in constructions such as w ciągu dwóch tygodni (within two weeks) or przez dwa tygodnie (for two weeks). The locative form tygodniach thus serves a distinct grammatical function, marking location in time rather than duration in many expressions.

Overall, tygodniach is a specialized grammatical form tied to indicating time expressed in weeks, and it appears in contexts where the discussion centers on weeks as a temporal framework.
