Tout est bien.
You say tout ira bien.
To say "It is okay" in French, you would normally say, "Ça va."
we say d'accord or okay.
You say, "is everything okay?"
Tout is French for everything.
d'accord
D'accord.
voila
J'espère que ça IRA/ que tout VA bien se passer.
Tout is French for everything.
'Okay' as an agreement is d'accord. To say that you are okay if someone asks you how you are, you could say 'comme ci, comme ca.'
I like everything is 'j'aime tout' in French.
