Pronunciation

  • /unˈθiɾ/, [ũn̟ˈθiɾ], /unˈsiɾ/[1]

Forms

uncir (first-person singular present unzo, first-person singular preterite uncí, past participle uncido)[1] Old Spanish wrote unzir; the Fuero Juzgo also has yunne, yunge and yunze.[2][3] Nebrija recorded uñir, still used in Leonese dialects and in northern Argentina;[4] unguir appears in 1267, and Aragonese has chunir and hunir.[2] Asturian has xuncir and xoncer, and Alava and Aragon juncir.[4][5]

Etymology

It is inherited from Old Spanish unzir, inherited from Latin iungō (“to yoke, join”).[2][6][7][1] The Latin group ⟨ng⟩ before ⟨e⟩ gave a voiced /dz/, written ⟨z⟩, as in Old Spanish renzilla and enzía; the other outcome, /ɲ/, gave the variant uñir.[2]

The loss of the Latin /j/- is unusual, since before ⟨u⟩ Spanish normally keeps it as ⟨j⟩.[2] Forms that kept it survive in Mozarabic yunnir of about 1100, Old Spanish junir and dialect juncir.[2] Corominas rejects E. H. Tuttle's idea that the initial palatal was taken for the pronoun ge.[2]

The same verb is Portuguese jungir, Galician xunguir, Asturian xuncir, Catalan junyir, Occitan jónher, French joindre and Italian giungere.[8][5][9] The Latin verb comes from Proto-Italic *jungō and Proto-Indo-European *yunégti, a nasal present of the root *yewg- (“to join, yoke”), the root of iugum (“yoke”).[1][10]

Earliest recorded meaning

The DCECH's first record is unzir in the Fuero Juzgo of 1240.[2][6] Alfonso X's General estoria (1272–1275) says that a man was the first to invent the cart and to bring it drawn by yoked oxen or beasts, bestias yonnidas.[11] A translation of Jacques de Vitry's history of Jerusalem, after 1350, lists the work of farmers: unzir los bueyes al carro “to yoke the oxen to the cart”.[12]

Semantic evolution

The Latin verb had the wide sense “to join”, and the 16th-century variant uñir kept it, both for joining things and, in Fray Luis de Granada, for spiritual union.[2] The standard verb narrowed to yoking animals: Autoridades in 1739 defined it as tying oxen or mules to the yoke for drawing.[13] Domínguez in 1847 added figurative senses, to subject someone to a yoke.[14] The VOX dictionary records a modern extension, to fasten a load to a thing or person.[15]
