какой корень в слове съел

you have received a letter from your English-speaking pen-friend Helen who writes:
...Next week I'll go to the French Conversation Club. I think it's a great opportunity to become fluent and confident. What about you? Have you ever participated in such events? What aspects of English are the most difficult for you? What helps you to learn English?
...Well, yesterday I went to the library...
Write a letter to Helen.
In your letter
- answer her questions
