Forms

reconocer (first-person singular present reconozco, first-person singular preterite reconocí, past participle reconocido)[1] Medieval forms include reconnoscer, recognoscer, reconosçer and Aragonese recoynnoscer and reconexer.[2][3][4]

Etymology

It is inherited from Latin recognōscō (“to recall; to examine, review”), in a Vulgar Latin form *reconōscō remade, like conocer from *conōscō, on the simple verb nōscō.[4][5][6][1] Corominas and DICCA-XV treat it instead as a derivative of that verb, and the Diccionario de Autoridades also called it a compound of the same verb with a prefix.[5][7][8][9]

The same Latin verb is Portuguese reconhecer, Catalan reconèixer and French reconnaître.[4][10][1] In late and feudal Latin the verb also meant “to confess” and “to acknowledge a lord's rights”.[10]

The Latin verb is formed from re- (“again, back”) and cognōscō (“to get to know”).[1][11] The simple verb goes back to Proto-Indo-European *ǵneh₃- (“to know”).[12]

Earliest recorded meaning

The earliest CDH hit is in the Fuero de Alcalá (c. 1235). A document of 1242 has the feudal sense: reconocemos por uostros omnes e por uostros uassalos “we acknowledge ourselves your men and your vassals”.[3] Corominas's first record is the Primera Crónica General, about 1280.[5][7]

Semantic evolution

Alfonso X's prose uses the verb for acknowledging dependence or a lord's authority, for admitting the truth of what another says or a debt of gratitude, and for “to consider, take note”.[2] Corominas also notes the senses “to confess” in Berceo and the Libro de Alexandre, and “to forgive” and “to thank” in the Rimado de Palacio.[5]

Covarrubias (1611) gives the military sense “to inspect ground or an enemy position”, and the sense “to acknowledge a benefit”.[13] Autoridades has “to examine carefully”, “to submit to another's rule” and “to confess an obligation of gratitude”.[9] The modern dictionary lists the medical examination, the recognition of a new state or government, and the legal recognition of a child.[6]
