What does french jai mean?

"Jai" is not a French word. It is likely you are thinking of the French word "J'ai," which means "I have" or "I am" in the present tense.

Here is a breakdown:

* J' is the contracted form of "je" (I)

* ai is the first person singular conjugation of the verb "avoir" (to have)

So, J'ai is literally "I have" but can also be translated as "I am" in certain contexts.

For example:

* J'ai faim (I am hungry)

* J'ai froid (I am cold)

* J'ai un livre (I have a book)
