Since you asked the question in English, I will give translations and some additional information: 1) belle = beautiful 2) jolie = pretty "belle" is stronger than "jolie". You can say a girl is pretty if she is nice to look at but not particularly so. "Belle" is used when the effect someone's appearance produces is stronger - someone who is particularly striking or unusual, like a model or actress.

En pratique, il y a très peu de différence entre "belle" et "jolie". De toute façon, la dame que vous qualifierez avec un de ces adjectifs sera très contente !

this question is about French, but I could not set it in additional info (I don`t know why)
