Który: which — and the comma English does not write

Który adds a second half to a sentence to describe a noun, like English who, which and that. Znam studenta, który mieszka w akademiku — I know the student who lives in the dorm. For example: “Znam studenta, który mieszka w akademiku” — I know the student who lives in the dormitory. A rule from the Polish course: worked out on examples, not memorized as a wording.

How it works

Który adds a second half to a sentence to describe a noun, like English who, which and that. Znam studenta, który mieszka w akademiku — I know the student who lives in the dorm.

It changes like an adjective: with gender — który, która, które — and with its role in its own half. English shows the role with who, whom and whose. Polish shows it in the ending: student, którego znam — the student I know; mieszkanie, w którym mieszkam — the flat I live in.

Polish always writes a comma before który, even where English writes none. Don't confuse it with że, that as in I know that: który always points back to a noun.

It also asks which one: Która godzina? — literally which hour, meaning what time is it?

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
