Termium plus

When Language Hat mentioned my post about Le grand dictionnaire, Arrogant Polyglot, "a Translator and a francophile fanatique," offered a link to another helpful online French dictionary: Termium Plus. You can get definitions of phrases, not just words, which is quite helpful for translating texts. Or you can get synonyms.

And while we're on the subject of French, I should also mention another powerful online tool. It's an online grammar and spellchecker for speakers of French (native or not). The tool, www.lepatron.ca, is a writing assistant rather than a corrector. Rather than correcting grammar and spelling errors automatically, it flags mistakes thereby allowing the user to introduce their own changes.

As I'm not a "francophile fanatique" like he is, I don't need that site, but it's still very cool in case you want to write correct emails and other French text.
