Questions & Answers about После разговора мне пришлось признать, что я был неправ.
Because после requires the genitive case.
- разговор = conversation (dictionary form, nominative)
- разговора = genitive singular
So:
- после разговора = after the conversation
This is a very common pattern in Russian:
- после урока = after the lesson
- после работы = after work
- после встречи = after the meeting
So the ending -а here is not random; it shows the noun is in the genitive after после.
Мне пришлось means something like I had to or it turned out that I had to.
Literally, the construction is impersonal. Russian often expresses necessity this way:
- мне пришлось = to me, it became necessary / fell to me
- natural English: I had to
The pronoun is in the dative because the experience or necessity is happening to the person:
- мне пришлось = I had to
- ему пришлось = he had to
- нам пришлось = we had to
This is a very common structure in Russian.
