Questions & Answers about Наша первая сессия оказалась сложнее, чем мы ожидали.

Why is it наша, not наш or наше?

Because сессия is a feminine singular noun. In Russian, possessive words and adjectives agree with the noun in gender, number, and case.

So in наша первая сессия:

• наша = feminine singular
• первая = feminine singular
• сессия = feminine singular

If the noun were masculine, you would get наш; if neuter, наше.

What case is наша первая сессия in?

It is in the nominative case because it is the subject of the sentence — the thing that turned out to be more difficult.

You can think of наша первая сессия as the answer to What turned out to be more difficult?
