Word Origin & History
wasp
O.E. wæps, wæsp, altered (probably by influence of L. vespa) from W.Gmc. *wabis- (cf. O.S. waspa, M.Du. wespe, Du. wesp, O.H.G. wafsa, Ger. Wespe, Dan. hveps), from PIE *wobhes-/*wops- (cf. L. vespa, Lith. vapsa, O.C.S. vosa "wasp," O.Ir. foich "drone"), perhaps from *webh- "weave" (cf. Gk. hyphos "web," O.E. webb "web," O.N. vefa "to weave"). If that is the correct derivation, the insect would be so called for the shape of its nest. Waspish in the sense of "irascible, spiteful" is attested from 1566. Wasp-waist is recorded from 1870.
