Forms
iaue f (oblique plural iaues)[1]
Early and regional spellings: egua in the Vie de saint Alexis, ewe from the Roland to the 13th century, eve in the 12th and 13th centuries, aive, eawe about 1290 and iaue.[2] Eastern and north-eastern awe, without the rounding of the vowel.[4]
Etymology
It is inherited from Latin aqua (“water”).[1][2][5][6] The Latin word continues Proto-Italic *akwā-, with cognates only in Germanic, Gothic 𐌰𐍈𐌰 (aƕa) and Old High German aha from Proto-Germanic *aχwō, and de Vaan notes that this Italic and Germanic word may have been borrowed from a non-Indo-European language.[7] Its Romance cognates include Italian acqua, Spanish agua and Romanian apă.[8]
In the Latin word the group /kw/ weakened to /w/ and the first vowel moved towards /ɛ/, which gave egua in the Vie de saint Alexis and ewe in the Roland.[9] Pope traces the regional outcomes: the west had the form of the Roland by the 11th century, the centre developed a glide and wrote eaue, and the north-east kept an unrounded awe.[3][4] In the west the /w/ later became /v/, giving eve and aive, while elsewhere it became a vowel, which led through the central form to French eau.[9]
Bloch and Wartburg take aigue, the head word of Tobler–Lommatzsch and the DÉCT, for a form borrowed from the South,[6] while the DHLF calls it both an old French form and a southern one.[10]
Earliest recorded meaning
The first record is the Vie de saint Alexis, which the DEAF bibliography dates to about 1090 and the TLFi to about 1050.[11][12] There the word, spelled egua, already means water poured out: L'egua li getent, si moilent sun liçon “they throw the water over him and wet his bed”.[12][13]
Semantic evolution
From the start the word named both the liquid and a stretch of it: the Roland has les ewes curant “the running waters”, and in Chrétien de Troyes it is a river to be crossed, deep water round a walled bailey, and sea water.[12][14] A text of 1185 uses it for a fluid of the body: l'eaue du cuer li est as yex montee “the water of the heart has risen to the eyes”.[12]
The spelling eaue lasted into the 16th century,[6] when the word was still said with two vowels; by the 17th century it was a single /o/.[3] The modern word is French eau, and the western eve survives in Poitou.[6]
Timeline
- c. 1090 – egua in the Vie de saint Alexis (about 1050 by the TLFi's dating).[11][13][12]
- c. 1100 – ewe in the Chanson de Roland, whose Oxford manuscript is Anglo-Norman of the second quarter of the 12th century.[15][16]
- 1104–1106 – ewe in the earliest Anglo-Norman text the AND cites for the word.[17]
- c. 1170 – eve in Chrétien de Troyes's Erec et Enide.[14][18]
- 1175–1200 – iaue in Garin le Loherain.[19][20]
- 1185 – eaue for a fluid of the body.[12]
- 1490 – the modern spelling eau.[12]
Meanings
Noun
- water, the liquid, also as one of the elements.[17][14]
- a body of water: a river, stream or the sea.[14][17]
- a flood.[17]
- a fluid of the body.[12]
Anglo-Norman
The AND heads the word ewe, first cites it from 1104–1106, and lists spellings from aeve and awe to yaue.[17] The AND records set phrases such as aler a l'ewe “to undergo the ordeal by water”, ewe beneite “holy water”, ewe de vie “brandy” and bailiff d'ewes, a water-bailiff or harbour-master.[17] Pope compares the English word ewer with the western form.[3]
