Pronunciation

Forms

chato (feminine chata, masculine plural chatos, feminine plural chatas)[1]

Etymology

It is inherited from Vulgar Latin *plattus (“flat, flattened”), a Greek loan in Vulgar Latin, from Ancient Greek πλατύς (platús, “broad, flat”).[2][3][4][1] The same word is Portuguese chato, French plat, Occitan plat, Catalan plat and Italian piatto, and the nouns plato and plata go back to it as well.[2][1][5] The Greek adjective continues Proto-Indo-European *pléth₂us, from a root meaning “flat”.[1]

The initial /tʃ/ from Latin /pl/ is the Portuguese outcome, where Castilian normally has /ʎ/, and the word is recorded late, so it may be a borrowing from Portuguese; the DLE speaks of Galician-Portuguese influence.[2][4][1] Corominas does not rule that out, but thinks it more likely a popular, affective word kept out of serious writing before the Golden Age, whose /tʃ/ arose after a consonant, in phrases such as ⟨un chato⟩, ⟨es chato⟩ and ⟨los chatos⟩.[2] He notes that the Portuguese word is no better attested in old texts.[2] The nouns used in Juan Ruiz's Libro de buen amor, applied to mountain girls, seem to him to mean only “highlander”, so they cannot date the adjective.[2]

The form ñato of the Americas comes from a cross with Leonese nacho (“snub-nosed”).[3]

Earliest recorded meaning

Boyd-Bowman's first record is from Mexico in 1575: people who tienen la cara larga y las cabeças chatas “have long faces and flat heads”.[6] Corominas's earliest records are Rosal's dictionary of 1601 and the first part of the Quijote (1605); in the second part Cervantes calls a village girl carirredonda y chata “round-faced and snub-nosed”.[2][7]

Semantic evolution

The Diccionario de Autoridades defines it as flat where a thing should be pointed or raised, above all of the nose, and of a person with a flattened nose, the same as romo.[7] Seventeenth-century writers mostly kept to romo, the more refined word.[2] From the start it also meant simply “flat”: Río de la Plata texts of 1581 speak of barcas chatas “flat-bottomed boats”, and chata “barge” is recorded from 1720.[6][3]

Modern Spanish uses it figuratively for dull or narrow-minded ideas, and as a noun for a low, wide wine glass in taverns; the feminine names a bedpan, a barge, and la chata is death.[4][8] In Spain it is an affectionate form of address, especially to children and to women.[8][1] In Peru, Bolivia, Chile and north-western Argentina it means “short”, in Chile “fed up”, and in Venezuela a business that brings little profit.[9][4] The Catalan word xato was taken from Spanish.[1]
