These two verbs are the very foundation of the French language. Without sound understanding of these two verbs, very little can be done in French.
ÊTRE - to be
Je Tu Il / Elle Nous Vous Ils / Elles
suis es est sommes êtes sont
AVOIR - to have
Je* Tu Il / Elle Nous Vous Ils / Elles
ai as a avons avez ont
N. B.
In French, it is preferable not to pronounce two vowel sounds in a row. As a result, the "e" in "je" is dropped and "je ai" becomes "j'ai" and is pronounced as one word.
It is important to note that the word "je" is not capitalized the way "I" is in English.
