Learn Polish: Rewolucja przemysłowa w osiemnastym wieku zmieniła naszą cywilizację. - The industrial revolution in the eighteenth century changed our civilization.

To say that something happened "in" a certain century, Polish uses the preposition w followed by the Locative case. The ordinal number osiemnasty (eighteenth) changes to osiemnastym (Locative masculine singular), and the noun wiek (century) changes to its Locative form, wieku.

Where does the adjective przemysłowa (industrial) come from?

It comes from the noun przemysł, which means "industry". By adding the suffix -owy (or in this case, the feminine -owa to match the feminine noun rewolucja), you turn the noun into an adjective.

Why is the verb zmieniła used here instead of zmienił?

In the Polish past tense, verbs must agree with the gender of the subject. The subject here is rewolucja, which is a feminine noun. Therefore, the verb takes the feminine past tense ending -ła, giving us zmieniła.

Why is it naszą cywilizację instead of "nasza cywilizacja"?
