Language apps on an iMac?

I am looking for a French/English dictionary and a French conjugation app to go on my iMac with Snow Leopard. Any ideas as to how I can find them please?

I have had a look at the apps on iTunes, but they only appear to be for the handheld kit...

Edit : - I had meant to say that I have both on my Touch and wondered if the same apps would work on my iMac, but I think not?

Here's a dictionary you can download. But as for a French verb conjugation app, I imagine that would require a French language learning software package which is not going to be free. Do some searching.

Regards.

Thank you CH. That looks as if it may have conjugation in it? That is my main failing and as we live here it's a good idea to at least try to get it correct sometimes!!

I'll have to look at it tomorrow as I turn into a pumpkin in about 2 minutes time, at midnight!

Thanks for your time!
