best
"mieux" or "meilleur"
You can say "You better" in French as "Tu ferais mieux".
"Mieux" in French is pronounced as "myuh" with the 'myu' sound similar to the English word "mew" with a soft 'y' sound.
Mieux.
The French word 'Lemieux' may be used as a last name. But it's made up of the combination of 'le' and 'mieux'. The word 'le' is the masculine definite article, which means 'the'. And the adjective or adverb 'mieux' means 'better'. But in combination, 'le mieux' means the best.
Il sentira mieux.
ça pourrait être mieux - peut mieux faire
ça pourrait aller mieux, je pourrais être mieux
Je suis mieux au francais=I am better at french (the language)
"bonne pour vous" is a bad word for word (machine) translation for "good for you", it does not exist as such in French, and it is already an answer, so you don't answer it. The French equivalent for "good for you" would be "tant mieux pour toi".
J'espère que vous vous sentez mieux, j'espère que vous allez mieux
... mais il essaiera de son mieux, il fera de son mieux
