Learn Croatian: Ja izujem tenisice u sobi. - I take off my sneakers in the room.

While skinuti is the general verb for taking off clothes or removing objects, izuti (and its imperfective form izuvati) specifically means to take off footwear, like shoes or socks. Its direct opposite is obuti (to put on footwear).

Izujem comes from the perfective verb izuti. Is it normal to use a perfective verb in the present tense like this?

Generally, perfective verbs in the present tense aren't used for actions happening right now (that would be the imperfective izuvam, meaning "I am taking off"). Used on its own like this, the perfective present describes a habitual or completed event, strongly implying a context like "Whenever I enter, I take off my sneakers."

Since the verb ending -m already means "I", why is the pronoun ja included?

Subject pronouns are usually dropped in Croatian. Adding ja here creates emphasis or contrast. The speaker is likely stressing that they take their sneakers off in the room, perhaps implying that someone else does not.

Why do we use u sobi (locative) rather than u sobu (accusative)?
