Forms

reconhecer (first-person singular present reconheço, first-person singular preterite reconheci, past participle reconhecido)[1] Old Galician-Portuguese wrote reconnocer, reconocer and reconecer;[2][3][4] reconheceo appears in the 14th century.[2][3][4]

Etymology

It is inherited from Latin recognōscō (“to examine, review; to recognise”), written Old Galician-Portuguese reconnocer in the oldest texts.[2][5][1][6] The Latin verb is formed from re- (“back, again”) and cognōscō (“to get to know”).[7][1]

The same Latin word is Galician recoñecer, Spanish reconocer, Catalan reconèixer, French reconnaître and Italian riconoscere.[1][8][9] The ending followed that of conhecer, whose old form Old Galician-Portuguese conhocer changed, according to Houaiss, by dissimilation of the two /o/ and under the influence of the suffix -ecer.[10]

Earliest recorded meaning

Charters of 1265 and 1268 have reconosco and me reconozco … por pagado “I acknowledge myself paid”, the sense “to acknowledge”.[3][4] Houaiss's first record is in the Cantigas de Santa Maria: sempre reconnocesse a Virgen e a loasse “that he should ever acknowledge the Virgin and praise her”.[2][3]

Semantic evolution

Acknowledging a lord was a central medieval use (reconhecendoo por senhor in the Crónica Geral of 1344).[3] Houaiss dates the sense “to admit as true” to the 15th century.[2] Bluteau (1712–1728) gives the sense “to come to know” and examples of acknowledging an error, and Morais (1789) adds recognising what one had forgotten, acknowledging vassalage, declaring a bastard to be one's son, and examining a place.[11][12] The modern senses also cover the legal recognition of a child, the recognition of a government, and gratitude for a favour.[2][13]
