I am a beginner and learned that they're all conjugated forms of être (to be). I'd like to know which ones I need to use.
The verbs in French are much more complicated to conjugate than in English. They change according to the subject, and the tense and modes are more numerous.
Être (to be) is among the most complicated because you cannot see the common radical.
- I am = je suis
- You are (singular) = tu es
- He is = il est
- We are = nous sommes
- You are (plural/polite form) = vous êtes
- They are = ils sont
When at school, I commonly used the Bescherelle, which is still a reference book for conjugation.
