This resource was created in error. However, a use may appear. The category referred to below was not a category for pages in French. It was a displayed category from Template:Lang that, on en.wikipedia, is hidden. All it shows is that there is some snipped of French on the page, that used the lang template to warn the browser to use an appropriate character set.
A way to learn a language is to practice translation. Google translate can be used to start, and dictionaries and grammars can help.
We have a few pages here in French. Help Wikiversity by translating them.
