Questions & Answers about Ona była w parku w zeszłym miesiącu.

What’s the role of the word Ona in this sentence?

Ona is the personal pronoun “she.” Polish is a pro-drop language, so you could omit it if context makes the subject clear (e.g. Była w parku…). Including Ona here either clarifies who you’re talking about or adds emphasis: “It was she who was in the park last month.”

How do you form the past tense of być, and why is it była here?

The past tense for Polish verbs uses a stem plus endings that agree in gender and number. For być (to be), the stem is by- and the endings for singular are: • -łem/ -łam (I m./ f.)
• -ś (you sg.)
• -ł/ -ła (he/she)
So był = “he was,” and była = “she was.” The -a ending shows feminine singular.

Why is it w parku and not w park or do parku?

1. w meaning “in” (static location) requires the locative case.
2. The locative of park is parku (root park-
   • -u).
3. If you used do (“to”), you’d indicate motion (“to the park”) and then need the accusative case (do parku uses the same form but with a different sense).
