Forms
conhecer (first-person singular present conheço, first-person singular preterite conheci, past participle conhecido)[1] Old Galician-Portuguese wrote connocer, connosçer and conhocer in the 13th century, with conoscer in 1277 and cognoscer in 1278;[2][3] conhecer and cõhoçer appear in the 14th century and cogescer in the 15th.[2][3]
Etymology
It is inherited from Latin cognōscō (“to get to know”), first as Old Galician-Portuguese conhocer and Old Galician-Portuguese connocer; the present form appears in the 14th century.[2][3][1] Latin ⟨gn⟩ became ⟨nh⟩: Corominas notes that most Romance languages continue a Late Latin cōnōscō, reshaped after the simple verb, and that Portuguese is almost alone, with Engadine and a few Alpine dialects of Italy, in keeping a trace of the ⟨gn⟩.[4]
The change of the second vowel from /o/ to /e/ is explained by Houaiss as a dissimilation of the two /o/ sounds, helped by the verbs in -ecer, and Nascentes also invokes that suffix.[2][5] Carolina Michaëlis saw in it the analogy of inchoatives from Latin -escere such as padecer, parecer and guarnecer.[6] Corominas lists the same change of ending in Catalan and in Moroccan Judaeo-Spanish.[4]
The same Latin word is Galician coñecer, Spanish conocer, Catalan conèixer, French connaître, Italian conoscere and Romanian cunoaște.[7][1] The Latin verb is con- added to nōscō (“to get to know”),[8][1] and the simple verb, older gnōscō, goes back to Proto-Indo-European *ǵneh₃- (“to know”).[9]
Earliest recorded meaning
Houaiss's first record is the participle conocido in 1254, from Cunha's index of medieval Portuguese.[2] In the troubadour songs the verb means “to know”, “to recognise” and “to come to one's senses”;[6][10] Estevan da Guarda writes of un corretor a que vi / vender panos, que conhoci “a broker I saw selling cloth, whom I recognised”.[6][10] The infinitive was also a noun, “judgement, opinion”: quant'é meu conhocer “as far as I can judge”, and a man sen conhocer was a fool.[6][10]
Semantic evolution
The legal sense of a judge hearing a case, conhecer de uma causa, is in Folqman's dictionary of 1755.[11] Morais (1813) begins with “to perceive with the mind” and records conhecer a mercê a alguém “to acknowledge a favour, be grateful”.[12] The biblical sense “to have sexual relations with” is now dated; in rural Portugal in the 1940s the verb was avoided with women for that reason.[13][14] Modern senses include “to meet for the first time”, “to visit a place” and “to go through, experience”.[2][1]
