Learn Hardcore Polish: Oni są w sklepie.

In Polish, Oni (they) is typically used for a group that includes at least one man or a mixed group (men and women). One is used for all-female groups or for things/objects. So if you have at least one man in the group, you use Oni.

Why is the pronoun Oni used at all if we already have the verb są?

In everyday conversation, Polish speakers often drop pronouns because the verb form already implies who is speaking, or about whom. However, including Oni can emphasize the subject or clarify who is being talked about. It's not strictly necessary, but it can be stylistically or contextually helpful.

Why do we say w sklepie and not w sklep?

In Polish, the preposition w requires its object to be in the locative case. Sklep becomes sklepie in the locative. You can recognize the locative case ending in -ie.

Why is the verb są used here?

Są is the third-person plural present tense of the verb być (to be). It matches the subject Oni (they).

Is the pronunciation of sklepie tricky for English speakers?

It can be slightly tricky because of the consonant cluster skl- at the start. Make sure to pronounce s and k distinctly before the l, and end with a clear -pie. Practice saying “skleh-pyeh” slowly, increasing speed as you get more comfortable.
