Old Norse
“For centuries, the English language ran two words in parallel — the Old English ey and the Norse egg — until a fifteenth-century printer named William Caxton complained that he could not tell which word a London merchant would understand, and the Norse word won.”
The English word 'egg' is Old Norse, not Old English. The native Old English word for the egg of a bird was ey (plural eyren), directly related to Latin ovum and German Ei. Old Norse had egg — the same word used by Danish and Norwegian settlers in the Danelaw from the ninth century onward. For several hundred years both forms coexisted in Middle English, sometimes in the same document, the northern dialects using egg and the southern dialects using ey or eyre. This is one of the most clearly documented cases of a Norse word defeating an Old English word in open competition.
The collision of the two words is famously documented in the prologue to William Caxton's Eneydos (1490), where Caxton recounts a story of a London merchant who asked for 'eggs' at a house in Kent and was told by the woman of the house that she 'could speke no Frenshe' — she understood ey or eyren, not eggs. Caxton used this anecdote to illustrate the bewildering dialect variation of English in his time, but he was also observing a competition that was nearly over: eggs was winning. The Norse form was displacing the Old English form across the south even as Caxton wrote.
Why did the Norse word win? Linguists have proposed several explanations. The monosyllabic egg was easier to handle than the two-syllable eyren when pluralized. The Norse settlers in the Danelaw were sufficiently numerous and economically significant that their vocabulary had genuine prestige in the north, and northern English trade networks carried the word south. There is also the simple phonological fact that egg remained stable across inflections while the Old English ey/eyren alternation was phonologically complex and eroding. By the sixteenth century, egg was the standard English word everywhere.
Old Norse egg descends from Proto-Germanic *ajją, which also produced Old English ey/eyren, German Ei, Dutch ei, and the Latin cognate ovum. The common ancestor goes further back still to Proto-Indo-European *h₂ōwyóm. The Norse word did not introduce a new concept — eggs had existed in English discourse since before the Norse contact — it introduced a new phonological form and then outcompeted the native one in the long linguistic tournament of post-Conquest English.

The word egg is now so fundamental to English that its foreign origin is effectively invisible. There is no English speaker who pauses over the word, no food item more basic to the culinary imagination, no word that seems more natively, primordially English. Which is exactly the point: the Norse settlers were not borrowing exotic vocabulary into English. They were replacing the most ordinary words, the daily words, the words for what you eat for breakfast.
Caxton's 1490 anecdote — the merchant who couldn't get eggs in Kent — is one of the great moments in English language history, a snapshot of a competition that had been running for five hundred years and was almost over. The Norse word won not through prestige or poetry but through the slow, patient accumulation of usage in daily speech. That is how the most important linguistic changes happen.
