Etymology
1. The noun is derived from Middle English eg, egg, egge (“egg of a domestic or wild fowl; egg of a snake”) [and other forms] (originally Northern England and Northeast Midlands), from Old Norse egg (“egg”), from Proto-Germanic *ajją (“egg”) (by Holtzmann’s law), from Proto-Indo-European *h₂ōwyóm (“egg”), probably from *h₂éwis (“bird”), from *h₂ew- (“to consume”). Doublet of huevo, oeuf, and ovum.
