Forms

zio m (plural zii, feminine zia, augmentative (uncommon) zióne, diminutive-endearing ziétto or (less common) ziìno or ziùccio)[1] Central and southern Italian shorten it to zi’ before a name, as in zi' prete.[2][3] Old forms zieso and ziso mean “his uncle”, and an old ziano was formed on the model of barbano.[4]

Etymology

It is inherited from Late Latin thīus (“uncle”), from Ancient Greek θεῖος (theîos, “uncle”).[5][6][7][1] Isidore of Seville, in the 6th–7th century, wrote of the Latin word “Tius Graecum est”, “tius is Greek”; the feminine thīa is also late, found in glosses.[5] The Greek words θεῖος (theîos) and θεία (theía, “aunt”) are fairly recent kinship terms of the language of young children, akin to Ancient Greek τήθη (tḗthē, “grandmother”) and τηθίς (tēthís, “aunt”).[5][6][2] Devoto notes that the Greek word was taken with its initial consonant already pronounced as an affricate.[8]

The same word is Spanish tío, Portuguese tio, Catalan tio, Sardinian tiu and Old Occitan sia.[6][9][10] Latin distinguished the father's brother and sister (patruus, amita) from the mother's (avunculus, matertera); French kept one word of each pair, French oncle and French tante, while the southern Romance languages took the Greek words, a choice paralleled by English uncle and German Onkel, later loans from French.[6][10]

DELI, following Aebischer, describes the two Latin words as the usual words of spoken Latin in southern Italy, from which they spread through Rome and Tuscany to northern Italy and the Iberian Peninsula, displacing the old Latin names and newer Germanic loans.[5] Meyer-Lübke too saw the word as southern at first, gradually ousting the Latin word for the aunt and barba “uncle” in the north; southern forms in ⟨-anu⟩ are a trace of the struggle with it.[9] Bertoldi explained the success of the word by its expressive force: the Greek word first meant “divine, magnificent” and came to convey authority or respect.[5]

Earliest recorded meaning

Nocentini dates zio to 1235 and zia to 1295;[6][5][7] DELI's first record is the Novellino of the late 13th century, in the sense “the brother of one's father or mother”.[6][5][7] DEI dates it to the 12th century.[11]

Semantic evolution

The Storie de Troia e de Roma have “Abbe in grande odio Amulio suo zio” (he greatly hated his uncle Amulius), and the account books of the Peruzzi company use the word in the 14th century.[3] The feminine zia is recorded in Giovanni Villani before 1348, and zio for the husband of an aunt only in 1961.[5] Prozio, the great-uncle, is recorded in 1640.[6]

In the south the shortened zi’ became a title of respect for old men and priests, as for zio Crocifisso in Verga's Malavoglia.[12][2] Zio Sam, the United States, translates English Uncle Sam, and lo zio d'America is the rich relative who emigrated and, from whom one hopes for an inheritance.[12][13] A Tuscan proverb says “Colui è mio zio, che vuole il ben mio”, he is my uncle who wishes me well.[14]
