How it works

English uses of, -en words and with for material and tools. Polish splits them into three patterns.

For material or source, use z plus the of-form, the shape a noun has after of: sweter z wełny, torba z naturalnej skóry, sok z jabłek. Before a cluster like sz or sk, z becomes ze: ze szkła, ze skóry.

The material can also be an adjective in -any or -owy: wełniany, skórzany, szklany, papierowy, metalowy. czapka z wełny and wełniana czapka mean the same.

A tool takes the instrumental, the with-form, and no preposition: kroić nożem, pisać długopisem, przykleić taśmą. Saying kroić z nożem is a mistake a Pole hears at once.

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.
