Forms
mío m sg (first person singular possessive of singular masculine, masculine plural míos, feminine mía, feminine plural mías)[1]
Etymology
It is inherited from Latin meus (“my, mine”); the Old Spanish form was mio.[2][3][1] Gómez de Silva traces it through a form *mieo from the Latin accusative.[4] Old Spanish texts also write myo and meo, and in the feminine mia and ma.[5][1] Before a noun the word was reduced to the unstressed mi in Spanish, as mon and mon are in Catalan and French.[6][7]
The same Latin word is Portuguese meu, Catalan meu, French mien, Italian mio and Romanian meu.[6] In Asturian mio is used after the noun for both genders, with feminine nouns too.[8]
The Latin word is formed on the stem of ego (“I”) with an adjective ending; the OLD compares a Hittite possessive.[9] Wiktionary gives Old Latin meos and *meos, and Gómez de Silva *me-yo- (“my”).[1][4]
Earliest recorded meaning
Corominas dates the word to 933.[2] In the Cantar de mio Cid (c. 1140, known from a 14th-century copy) the form mio stands before the hero's title, mio Cid.[10][11] The Auto de los Reyes Magos (c. 1180) has it before nouns too: „Uenga mio maiordoma, qui mios aueres toma” “let my steward come, who looks after my goods”.[10]
Semantic evolution
In Old Spanish mio could stand before the noun with or without the article (mio entendimiento in Alfonso X's prose); the reduced form mi took over this position, and mío kept the position after the noun and the use as a pronoun.[12][7] Covarrubias in 1611 describes this alternation (mi casa but casa mía) and records the proverb lo mío, mío, y lo tuyo de entrambos, which mocks greedy people.[7] The Diccionario de Autoridades adds es muy mío “he is a close friend of mine” and soy mío “I am my own master”, after Latin meus sum.[13] It and the Academy's dictionary of 1817 also record mío as the call for a cat.[13][14]
After certain nouns it expresses affection (hijo mío, ¡madre mía!).[15][16] Los míos are the speaker's family or group, lo mío what suits the speaker, and de mío “by myself, on my own resources”.[16][17][3] In Cuba mío or mía is a person one feels close to.[18]
