Pronunciation

  • Balearic, Central, Northern: [ˈaj.ɣwə][1]
  • Northwestern, Valencia: [ˈaj.ɣwa][1]

Forms

aigua f (plural aigües)[1] Old Catalan wrote aygua and ayga.[2][3][4] The spelling aigo appears in a Mallorcan account book of 1441.[5] The pronunciation varies across the language area: àigua in most of Catalonia and the north of Valencia, àiga in Roussillon and in a belt from Andorra through the Penedès and the Vallès, àigo in Mallorca and àigu in Menorca and Formentera; much of Valencia, south of Castelló, has a pronunciation with /aw/ in the first syllable.[2][6]

Etymology

It is inherited from Old Catalan aygua, the usual spelling of the medieval texts, which is inherited from Latin aqua (“water”).[2][6][7][8][1]

The same Latin word is Occitan aiga, Spanish agua, French eau, Italian acqua and Romanian apă.[9][1] The troubadours wrote Old Occitan aigua as Old Catalan did.[10][11]

The /i/ before the consonant, in the Catalan word as in Occitan aiga, is unexpected.[2] Coromines finds no satisfactory explanation for it; he mentions, without accepting either, a Latin pronunciation that split /k/ and /w/ between two syllables, and the variant spelt ⟨augua⟩, which is easier to explain and is recorded in scattered points of the Peninsula and southern France.[2] Spanish dialects, Leonese and Aragonese also have forms with /w/ moved into the first syllable.[12]

The Latin word comes from *akʷā; its closest cognates are Germanic, 𐌰𐍈𐌰 (aƕa) and aha.[13] Wiktionary takes it back to *h₂ekʷeh₂.[1]

Earliest recorded meaning

Coromines gives as the first record a document of 1169 in the cartulary of Poblet, which speaks of boschages et las aiguas “woods and waters”.[2] In 1204 a rule of the Templars allows a brother's wine to be taken away and water given him instead (tolre son vi e dar-li ayga).[2][6] In these first records the word means water, and in the plural the waters of an estate.[2]

Semantic evolution

In the medieval language aygua also meant a river or stream: the Catalan Vides de sants translate Latin fluvium with it, Llull describes a plain “through which a fine water ran”, and Desclot tells of crossing “a great water” in 1283.[2][5] The use survives in Pyrenean place names, such as l'Aigua de Valls at Gósol and l'Aigua d'Òra.[2]

Medieval writers also used the word for body fluids (urine, tears, the humours of an eye disease), for the juice of fruits, and for the lustre of pearls and diamonds.[5] Its derivatives are old: aigual is recorded in 976, from Latin aqualis, aiguader and aigüera “sink” in the 13th century, aiguat “downpour” in the 14th.[7]

Fabra's dictionary of 1932 still defines the word first as the liquid that falls from the clouds as rain and forms rivers, lakes and seas.[14] The DIEC2 defines it chemically, as a compound of hydrogen and oxygen, H₂O.[15]
