Bon travail !
English explanations:
- L' is "Le" (when followed by a word beginning with a vowel), so "The" as you expected yeah
- Anglais : English (either the language or the people, here about the language)
- Sympa : Yeah, comme from Sympathy, but here meaning like "Fun"
- Communiquer : Like English Communicate. The end in "-er" mark it as a verb, like in English adding "To" before: "To communicate"
- Croiser : Similar to English: to Cross (here meaning "gathering together at the same place" or smthg)
- Une : Singular form here yes. "une multitude" is a strangely singular word, meaning to talk about a lot of things as one single group
- ça : means "it" in French. The thing under the c (cédille: ç) like in Turkish, is to make it sound like "s" instead of default prononciation sounding like "k"
