Questions & Answers about Ekipa je u kafiću.
Because ekipa is grammatically singular in Serbian. It is a collective noun: it refers to multiple people, but the noun itself is singular, so the verb must also be singular.
- Ekipa je... = correct
- Ekipa su... = not standard here
This is similar to how English sometimes treats words like team or group as singular.
Yes. Ekipa is a feminine singular noun. One clue is that it ends in -a, which is very common for feminine nouns in Serbian.
That matters for agreement:
- Dobra ekipa je u kafiću. = The group is good / nice.
Here dobra is feminine singular to match ekipa.
