Pronunciation
Forms
desertar (first-person singular present deserto, first-person singular preterite desertei, past participle desertado)[1]
Etymology
It is borrowed from French déserter according to Cunha, Aurélio, Priberam, the DLP and the Porto dictionary, and the French verb is from Late Latin dēsertō (“to abandon”), the frequentative of Latin dēserō (“to leave, abandon”).[2][3][4][5][6][1] Houaiss derives the Portuguese verb directly from the Late Latin one.[7] Figueiredo, Silva Bastos and Michaelis instead form it from Portuguese deserto + -ar.[8][9][10]
Medieval Latin used the verb for “to abandon” and “to lay waste”, and a capitulary of 805 already has it in the sense of the classical verb.[11][12] The French verb is itself a borrowing from Late Latin, and Spanish desertar is taken from the Latin verb too.[1][13]
Earliest recorded meaning
Houaiss dates the verb to 1632; a private letter of 1669 has the participle decertado.[7][14] Bluteau marks it as a military term: for a soldier, to flee and leave the camp, army, garrison or regiment he belongs to.[15]
Semantic evolution
Feijó (1734) records a legal use, in lawsuits, for a thing left or abandoned.[16] Morais (1789) defines only the military sense, to leave the service without leave, meaning to quit it for good.[17] Vieira adds “to depopulate, make a place deserted”, the forensic “to abandon a case”, and the abandoning of a country, a party or a post.[18]
The modern dictionaries add going over to the other side, giving up an idea, a feeling that leaves someone, and the withdrawing of a horse from a race.[7][19] The old Aulete also uses it of a horse that bolts.[19][4]
