Old English wæps, wæsp, altered (probably by influence of Latin vespa) from West Germanic *wabis- (cf. Old Saxon waspa, Middle Dutch wespe, Dutch wesp, Old High German wafsa, German Wespe, Danish hveps), from PIE *wobhes-/*wops- (cf. Latin vespa, Lithuanian vapsa, Old Church Slavonic vosa "wasp," Old Irish foich "drone"), perhaps from *webh- "weave" (see weave (v.)). If that is the correct derivation, the insect would be so called for the shape of its nest. Wasp-waist in reference to women's figures is recorded from 1870 (wasp-waisted is from 1775).
