Forms

rotundo (feminine rotunda, masculine plural rotundos, feminine plural rotundas)[1]

Etymology

It is borrowed from Latin rotundus (“round, wheel-shaped”), a learned word.[2][3][4][1] The Latin adjective is derived from rota (“wheel”).[2][5] The OLD takes it to have been a verbal adjective in origin, like secundus, and Wiktionary reports de Vaan's suggestion that its vowel was coloured by the noun for “wheel”.[5][1]

The inherited doublet is redondo, from the variant Vulgar Latin *retundus.[1][6][7] The Latin word lives on in the same way in Spanish redondo, Catalan rodó, French rond, Italian tondo and Romanian rătund.[8]

Earliest recorded meaning

Houaiss dates the word to 1572, the year of Os Lusíadas.[2] Bluteau quotes its line from the seventh canto, Curral de quem governa o Ceo Rotundo “the fold of Him who rules the round heaven”, where the word has its Latin sense “round”.[9]

Semantic evolution

Bluteau and Morais give only “round”, and Bluteau also lists the title Nossa Senhora a Rotunda, given to the Virgin from the round shape of a temple.[9][10] The figurative sense “fat, corpulent” is recorded by Cunha and illustrated in the old Caldas Aulete with a line of Garrett about the rotunda figure of Sancho Panza.[3][11] The modern dictionaries add “categorical, flat”, said above all of a refusal or a denial, and the DLP also has “total, absolute”.[12][13][11]

Cunha dates the derivative rotundidade to the 17th century, rotundifólio to 1874 and the noun rotunda to 1881.[3]
