julio1 July
Etymology tree of julio1
Pronunciation
- /ˈxuljo/, [ˈxu.ljo][1]
Forms
julio m (plural julios)[1] Old Spanish texts spell it julio, iulio, jullio and iuliyo.[2]
Etymology
The word for July is borrowed from Latin Iūlius (“July; of the Julian family”), the name given to the month in honour of Julius Caesar.[3][4][5] Corominas and the BDELC treat it as taken from Latin, a word in general use at every period;[3][4][1][6] Wiktionary calls it inherited and probably semi-learned, and García de Diego leaves open whether it is a learned word or a reaction against the popular forms of the dialects around Burgos.[3][4][1][6]
In the Ibero-Romance languages popular forms such as Portuguese julho were used at first everywhere, but the learned forms soon came into Castilian.[7] Catalan and French turned to the diminutives Catalan juliol and French juillet, which kept the month apart from June better.[7] Other forms of the same word are Italian luglio, Occitan julh, Galician xullo and Asturian xuliu.[1][8]
The Latin month was earlier called quīntīlis (“fifth”) and was renamed after Julius Caesar in 44 BC.[1][9] The family name may be a contraction of an Old Latin personal name *Iovilios (“descended from Jove”), or come from Ancient Greek ἴουλος (íoulos, “first down of the beard”).[1]
Earliest recorded meaning
The first hit in the CDH is the Semejanza del mundo of about 1223: anda el sol en todo el mes de jullio “the sun moves through the whole month of July”.[10] Corominas and the BDELC date the word to Berceo's Vida de San Millán (1220–1250).[3][4]
Semantic evolution
Covarrubias in 1611 explained that the month, the fifth counting from March, had lost the name Quintilis in honour of Julius Caesar, who was born in it.[11] Autoridades called it the fifth month in the first Roman calendar and the seventh in the later Roman and Church reckoning, with 31 days.[12] A record of 1554 from Peru names July together with its Inca name.[13] The word was borrowed into Tagalog as Hulyo and into other languages of the Philippines.[1]
