1744, from Du. wafel "waffle," from M.Du. or M.L.G. wafel; cognate with O.H.G. waba "honeycomb" (Ger. Wabe) and related to O.H.G. weban, O.E. wefan "to weave" (see weave). Sense of "honeycomb" is preserved in some combinations referring to a weave of cloth. Waffle iron is from 1794.
1698, "to yelp, bark," frequentative of waff "to yelp" (1610); possibly of imitative origin. Figurative sense of "talk foolishly" (1701) led to that of "vacillate, equivocate" (1803), originally a Scottish and northern Eng. usage.
