Forms

teatro m (plural teatros)[1] The first record has theatros; the spelling teatro is recorded from 1836, and theatro was the usual form until the 20th-century reforms.[2][1] Pereira already heads the word Teatro in 1697, but Bluteau and Vieira refer teatro to theatro.[3][4][5] Feijó in 1734 lists the popular form tiatro beside theátro; dialect surveys of Portugal record treato and triato.[6][7]

Etymology

It is borrowed from Latin theātrum (“theatre”), from Ancient Greek θέατρον (théatron, “a place for viewing”), a learned word.[2][1][8][9] The same Latin word gave Galician teatro, Spanish teatro, Catalan teatre, French théâtre, Italian teatro and Mirandese triato.[1][10][11]

The Greek noun is formed on θεάομαι (theáomai, “to watch, look at”) with the instrumental suffix -τρον (-tron).[1][12][2] Houaiss starts from θέα (théa, “sight, spectacle”) and renders the whole literally as “machine for a spectacle”.[1][12][2] Nascentes remarks that the idea of seeing, not of hearing, came first, as in espetáculo.[8]

Earliest recorded meaning

Houaiss dates the first record, theatros, to the 15th century, in the sense of the great amphitheatre of ancient Rome where games and public shows were held.[2]

Semantic evolution

Bluteau in the 18th century described the theatre of the ancients, with its proscenio and orchestra, as the place where people gathered to see tragedies and comedies.[13] Morais in 1789 defines it as the place where plays are performed, and adds the figurative o theatro do mundo and as regras do theatro.[14] The original Caldas Aulete quotes Camões for the sense “circus, amphitheatre” and adds the dramatic works of an author or a country (o teatro italiano) and the art of acting.[15] From “stage” came “the scene of a notable event”, as in teatro de operações, and in recent use “pretence, a show of feeling”.[2][1][16]

Through Konkani the word reached English as tiatr.[1]
