Thank you very much! After some changes in the code (.MatchWholeWord = False and .MatchCase = False) your macro generated 540 footnotes of the whole 600. Sometimes the root of Hungarian words alter after conjugation, so I guess the rest would be tricky to solve.
Just another question if I'm not importunate. Is it possible to insert not only the definition, but both the term AND definition (something like: "term - definition") in footnotes?
