Wow....and I thought I was the only one with a passion for linguistics!
First of all, I'd like to make a correction to Perun's post.
[!--QuoteBegin--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--QuoteEBegin--]Gaelic is a Celtic language. It is related to dialects of Wales, Ireland, the Bretagne and northwestern Spain. The Celts reached these territories before the Germanics could have too much of an impact on them, and by the time the Germanics expanded, they couldn't have anymore impact on the languages[/quote]
I think you mean Northwestern France (Britanny), rather than Spain. I'll attribute that to a brain fart!
Point of interest - the Celtic peoples once occupied most of Northwestern Europe, before the Romans and later Germanic migrations pushed them to the fringes of the continent (Ireland, Wales, Cornwall, Scotland). The Celtic language spoken in Britanny, France is the result of a migration of Celtic peoples from Britain between 400-500 AD, when the Roman Empire was falling apart.
Due to massive migrations in the mid-1800's, a Celtic language is now spoken (as a second language) by many in my home, Nova Scotia (Lat "New Scotland").
Now, syl, to correct you [!--emo&

[!--QuoteBegin--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--QuoteEBegin--]Basque is unique in Europe but there are now evidences that it's related to caucasian and na-dene ( a family of languages of the native americans)[/quote]
Last I read, the supposed link between basque and a proto-Caucasian language was still being investigated; although it appears promising, nothing has yet been satisfactorily proven.
As for the relation to a New World language, this is just false. It is the fabrication of conspiracy theorists like Erik von Daniken (Chariots of the Gods, Gods from Outer Space, etc.)
NOW! As for the answer to my question, I was looking for the three which are most closely related, and you're both right!
German, English, and Flemish are quite similar in structure and form, all sharing a common ancestor.French and Latin are daughter and mother. Russian and Polish are both Slavic, and the other languages belong to their own groups!
Interestingly, Flemish is the closest linguistic relative to modern English, both in terms of grammar and vocabularly.
And I'm done.
