Forms

necessitar (first-person singular present necessito, first-person singular preterite necessitei, past participle necessitado)[1]

Etymology

It is borrowed from Medieval Latin necessitō (“to compel, constrain”), a learned word.[2][3][4][1] Du Cange notes that the Medieval Latin verb was often used by the Schoolmen.[5] The DLP, Michaelis and DELPo instead form it in Portuguese from Latin necessitās (“necessity”) with the verb suffix -ar.[6][7][8] Spanish necesitar is first recorded in the 17th century.[9]

The Latin noun is formed from necesse (“unavoidable”) with the abstract suffix -tās.[10][1] Its Portuguese descendant is the noun necessidade, recorded from 1365.[11]

Earliest recorded meaning

Houaiss's first record is from 1552, from a text he cites as JBarD;[2][3] Cunha gives the 16th century.[2][3] A private letter dated by 1542 already has the participle neçesytado “in need”.[12]

Semantic evolution

The usual sense from the start is “to need, to lack”, construed with a direct object or with de;[2][13] Bluteau (1712–1728) gives it as haver mister “to have need” and lists phrases such as necessito de ti.[2][13] The Medieval Latin sense “to compel” survives in Vieira (1871–1874), who puts “to urge, force, oblige” and “to cause needs” first, and in the rare senses “to force someone” and “to deprive of what is needed” that Houaiss and Aurélio still list.[14][2][15] Priberam marks the sense “to deprive of the necessary” as old.[16] Schlee records the indirect construction necessitar de as Brazilian usage in Rio Grande do Sul.[17]
