egg

{{11}}egg (n.) mid-14c., from northern England dialect, from O.N. egg, which vied with M.E. eye, eai (from O.E. æg) until finally displacing it after 1500; both are from P.Gmc. *ajja(m) (Cf. O.S., M.Du., Du., O.H.G., Ger. ei, Goth. ada), probably from PIE *owyo-/*oyyo- "egg" (Cf. O.C.S. aja, Rus. jajco, Bret. ui, Welsh wy, Gk. oon, L. ovum); possibly derived from root *awi- "bird." Caxton (15c.) writes of a merchant (probably a north-country man) in a public house on the Thames who asked for eggs:

And the goode wyf answerde, that she coude speke no frenshe. And the marchaunt was angry, for he also coude speke no frenshe, but wolde have hadde egges, and she understode hym not.

She did, however, recognize another customer's request for "eyren." Bad egg in the figurative sense is from 1855. To have egg on (one's) face "be made to look foolish" is attested by 1948.

[Young & Rubincam] realize full well that a crew can sometimes make or break a show. It can do little things to ruin a program or else, by giving it its best, can really get that all-important rating. They are mindful of an emcee of a variety show who already has been tabbed "old egg in your face" because the crew has managed to get him in such awkward positions on the TV screen. ["Billboard," March 5, 1949]

Eggs Benedict attested by 1898. The figure of speech represented in to have all (one's) eggs in one basket is attested by 1660s.

{{12}}egg (v.) c.1200, from O.N. eggja "to goad on, incite," from egg "edge" (see EDGE (Cf. edge)). The unrelated verb meaning "to pelt with (rotten) eggs" is from 1857, from EGG (Cf. egg) (n.). Related: Egged; egging.
