Questions & Answers about Sklep otwiera się o dziesiątej.
Why is się attached to otwiera in Sklep otwiera się o dziesiątej?
się is a reflexive particle that turns the transitive verb otwierać (“to open something”) into an intransitive or passive-like form (“to open” on its own). So Sklep otwiera się means “the shop opens,” not “opens something.”
Why is the verb in the present tense when the opening time is in the future?
Polish uses the present tense for scheduled or habitual events (timetables). Here otwiera się describes a regular schedule: “it opens at ten.” To talk about a single future event, you’d use the perfective future: Sklep otworzy się o dziesiątej (“The shop will open at ten”).
What does the preposition o mean before dziesiątej?
In time expressions o means “at” (a point in time) and it requires the locative case. So o dziesiątej literally means “at the tenth (hour),” i.e. “at ten o’clock.”
Why is it dziesiątej instead of dziesiąta or dziesiąty?
Dziesiątej is the ordinal “tenth” in the locative case, singular feminine. Two reasons: 1) the preposition o governs the locative; 2) godzina (hour) is feminine, so the ordinal agrees in gender and case (implied: o dziesiątej godzinie).
Can I just say Sklep otwiera o dziesiątej without się?
No—without się, otwierać is transitive (“to open something”). Sklep otwiera o dziesiątej would mean “The shop opens (something) at ten,” which is incomplete. You need się to express “opens” intransitively.
How would I ask “What time does the shop open?” in Polish?
You can say O której otwiera się sklep? or O której sklep się otwiera? Both literally mean “At what time does the shop open?”
What’s the difference between otwierać się and otworzyć się?
Otwierać się is the imperfective form (“it opens,” habitual or ongoing), used for timetables and regular actions. Otworzyć się is perfective (“it will open,” single completed event). Timetables normally use the imperfective present.
