Forms

inteiro (feminine inteira, masculine plural inteiros, feminine plural inteiras)[1] The older form is enteiro, recorded in a Latin charter of 1093 and in the 13th century;[2][3] inteiro appears in the 14th century.[2][3]

Etymology

It is inherited from Latin integer (“untouched, whole”), through the popular form, written Old Galician-Portuguese enteiro in the oldest texts.[2][4][1] In spoken Latin the stress moved to the second syllable, and the /g/ before /r/ became /i/.[4][5][6] The initial ⟨in⟩ of the modern form was restored after the Latin word.[4][1] The learned doublet is íntegro.[2][1]

The same Latin word is Galician enteiro, Spanish entero, French entier, Italian intero and Romanian întreg.[7][1] The Latin adjective is formed from in- (“not”) and the root of tangō (“to touch”), so that it first meant “untouched”;[8][1] Umbrian has a related form.[8][1]

Earliest recorded meaning

Houaiss's first date, 1093, is the form enteiro in a Latin charter.[2] In the Cantigas de Santa Maria the word already has the senses “whole, complete” (un an'enteir' “a whole year”, un gran livr'enteiro “a whole big book”) and “intact” (a virgin who stayed enteira).[3]

Semantic evolution

Cardoso in 1569 glosses it with Latin integer, and Bluteau in 1712 defines it as having all its parts.[9][10] Morais in 1813 adds the arithmetical sense “without fractions” and dia inteiro “a whole day”.[11] Figurative senses, “upright, incorruptible” and “without reservation”, stand beside the physical ones.[2][12]

Of animals it means “not castrated”, a sense common in rural Brazil and Portugal, and irmãos inteiros are children of the same father and mother.[2][13] The word passed into Malay as antero and into the Malay of Ambon and the North Moluccas as anteru.[1]
