Questions & Answers about После разговора с учителем мне стало понятнее, как работает это правило.
Because после requires the genitive case.
- разговор = nominative singular
- 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 here, разговора is simply the form required by после.
Here с means with, and in that meaning it normally takes the instrumental case.
- учитель = teacher
- учителем = instrumental singular
So:
- разговор с учителем = a conversation with the teacher
Be careful: с can take different cases depending on meaning.
- с учителем = with the teacher → instrumental
- с горы = from the mountain → genitive
In this sentence, it clearly means with the teacher, so instrumental is used.
