Recently, I've been learning French language and I've noticed that many words in English have similar words in French, for example the word “example” in English and the word “exemple” in French. If I want to use this rule to guess the meaning of some French words by comparing to their English brothers, I have to be careful about the counterexamples, the words that are spelled similarly in French and in English, but have very different meaning in each language. For example, the word “comment” in English and in French.
Therefore I'd like to know: Is there any (preferably online) list of such (counterexample) words in French & English?
Of course, I don't need an exhaustive list of all counterexamples of the above rule. A short list of very commonplace words would be more useful.
