Pronunciation

Forms

cū f (nominative plural cȳ)[1] Genitive singular cū, cūe or cūs; dative singular cȳ; genitive plural cūa or cūna; dative plural cūm.[2][3] The laws of Ine have the genitive cuus.[4] The Vespasian Psalter gloss has the accusative plural cȳe and the Rushworth gloss the genitive plural cȳna.[5]

Etymology

It is inherited from Proto-West Germanic *kō (“cow”), from Proto-Germanic *kōz.[1][6] The other Germanic languages have Old Norse kýr, Old Frisian kū, Old Saxon kō and Old High German kuo.[6][7][8] Kroonen explains it as a root noun that continues the common Indo-European word for the cow, the u-stem Proto-Indo-European *gʷéh₃-u-s, oblique *gʷh₃-u-, itself made to the root Proto-Indo-European *gʷeh₃- (“to graze”).[6] The same word is Ancient Greek βοῦς (boûs, “ox, cow”), Latin bōs and Old Irish bó.[7][9]

Germanic had two forms of the stem, *kō- and *kū-, from one paradigm with a nominative in ō and an oblique stem in ū;[6] Old English and Old Frisian have the ū of the oblique cases, Old Saxon and Old High German the ō of the nominative.[6] In Old English it is a feminine root noun.[10] Its endings should all have been lost except in the dative plural ⟨cūm⟩, while the dative singular and nominative plural ⟨cȳ⟩ keep i-umlaut.[5]

Earliest recorded meaning

The word is first recorded in the will of Abba, a Kentish reeve, dated 833×839 and surviving in a contemporary single sheet.[11] If Abba's wife will not keep the land, it is to pass on, and he is to be given IIII oxan & II cy & L scepa & ænne horn “four oxen and two cows and fifty sheep and a horn” with it.[12][11]

Semantic evolution

Old English used the word only for the cow; a young cow or heifer was an iung cū.[2] It renders Latin “vacca” and “bucula” in the glossaries, and is named in wills and in the laws, where the laws of Ine have clauses on a cow's horn and a cow's eye.[2][4] In the medical texts cow's milk and dung are ingredients.[2][12]

The word lived on as Middle English cou, English cow; in English it came to be used of the females of other large animals from the late fourteenth century.[13][14]
