- equivocation
- late 14c., "the fallacy of using a word in different senses at different stages of the reasoning" (a loan-transl. of Gk. homonymia, lit. "having the same name"), from O.Fr. equivocation, from L.L. aequivocationem (nom. aequivocatio), from aequivocus "of identical sound," from L. aequus "equal" + vocare "to call" (see voice).
