II

a silly person, Irish dreólán, Welsh drel, a clown; from English droll? Thurneysen prefers to consider these words borrowed from English thrall, Norse þ;r$$oel. The word appears as dreòlan, dreallaire, drollaire. In the sense of "loiterer", these words are from the Norse drolla, loiter, English droil.
