Bilingual dictionaries

I always tell people to beware of bilingual dictionaries. One of the many reasons why: by looking up the Hungarian word vél in this dictionary, one finds as its first translation trow, which is a fine English word, but one almost nobody knows for its 'archaicness'. Here is its definition in English. A Hungarian might as well use trow speaking English under the impression it is an everyday English word, and all he would get is puzzled looks from regular English speakers.
