If you go to http://www.ceantar.org/Dicts/search.html
and search for
duck you will get tunag for duck and lach for wild duck in gaelic. Be
sure that you choose word, not headword as search type before you press
search on the search page. You won´t get anything with headword.
MacBain´s must be taken with a whole bucket of salt, though, because
there are errors here and there. Be warned.
