Questions & Answers about Ova situacija je problem.
Because ova has to agree with situacija in gender, number, and case.
- situacija is feminine
- it is singular
- here it is in the nominative
So the correct form of this is ova.
Compare:
- ova situacija = this situation
- ovaj problem = this problem
- ovo pitanje = this question
So English this has one form, but Croatian changes the form to match the noun.
Usually, yes. In Croatian, nouns ending in -a are very often feminine, and situacija is one of them.
So:
- situacija = feminine singular noun
- nominative singular form = situacija
That is why it combines with ova and with the singular verb je.
There are some exceptions in Croatian, but for a learner, -a often means feminine is a very useful rule.
