Pronunciation

Forms
tío m (plural tíos, feminine tía, feminine plural tías)[1] Old Spanish documents write tio, thio, tyo and thyo.[2] Old Aragonese had a form tiyo.[3]
Etymology
It is inherited from Old Spanish tio, inherited from Late Latin thius (“uncle”), which is from Ancient Greek θεῖος (theîos, “uncle”).[4][5][1] The feminine tía is likewise thia, from θεία (theía).[4] Isidore of Seville already calls tius a Greek word, glossing it with patruus (“father's brother”).[6] Niermeyer records the spellings Medieval Latin thius and zius for a father's brother.[7]
The same Late Latin word is Portuguese tio, Galician tío, Catalan tio, Sardinian tiu and Italian zio.[8][3][1] In Portuguese, as in Spanish, it replaced avunculus and the classical word for a father's brother.[9] Meyer-Lübke notes that in Italy the word belonged first to the south and spread north at the expense of older words for “uncle”.[8]
The Greek noun is first found in Attic;[10] Beekes suggests an onomatopoeic origin with a suffix, and compares the reduplicated τήθη (tḗthē).[10]
Earliest recorded meaning
Corominas dates the word to the second half of the 10th century.[4] The DEMel's first dated records are charters of Nájera (1117), Santo Domingo de la Calzada (1156) and Oviedo (1157), all in the sense “uncle”.[2] The Judizios de las estrellas of Alfonso X (1254) speaks of the profit a man will have „de sos tios de partes del padre” “from his uncles on his father's side”.[11]
Semantic evolution
From the start the word named the brother of a parent and, more loosely, a parent's cousin;[12] Autoridades (1739) says it is taken broadly for the collateral relatives of a higher degree, called second or third uncle according to the degree.[12] Autoridades also records that country people used it as a title for older men, and the phrase a tu tía, que te dé para libros, used to send away someone asking for something.[12] The Academy's 1884 dictionary adds the familiar sense “rustic, coarse man” and the phrase tener uno tío en las Indias “to have a rich, influential patron”.[13]
In modern colloquial Spanish of Spain tío and tía mean any man or woman whose name is unknown or not given, a person praised or blamed (¡qué tío!), and, above all among young people, a form of address to a friend.[5][14][1] In parts of Aragon and Castile the feminine has meant “stepmother”, and the masculine “stepfather”, sometimes “father-in-law”.[5][14] In Argentina it was once a title given to old Black men, and in the mining regions of Bolivia and north-western Argentina el tío is the devil or spirit believed to own the mine.[15][14][16] The obsolete feminine sense “prostitute” is still listed by the Academy.[5]

Usage notes
The phrase no hay tu tía “there's no remedy” is a false separation of no hay tutía, from the medicine tutía.[21] Tío bueno or tía buena is a vulgar expression for an attractive person.[5] In Chile the cuento del tío is a swindle;[22] Román traces it to the phrase tener un tío en las Indias.[22]
