Forms

duvidar (first-person singular present duvido, first-person singular preterite duvidei, past participle duvidado)[1] Old Galician-Portuguese had dovidar beside dultar and duldar;[2][3] Houaiss also records dudar in the 14th century and duuydar in the 15th.[2][3] Feijó's spelling guide of 1734 sets duvidar against dovidar.[4]

Etymology

It is inherited from Latin dubitō (“to doubt, hesitate”), written Old Galician-Portuguese dovidar in the oldest texts.[3][2][1] Corominas notes that the ⟨i⟩ of the Portuguese verb shows a semi-learned form, as do Italian dubitare and the ⟨bt⟩ of Catalan dubtar, whereas French douter and Old Occitan dobtar are popular.[5] The medieval Old Galician-Portuguese duldar and Old Galician-Portuguese dultar, shared with Old Leonese, are the more popular outcomes.[6][2]

The same Latin verb is Galician dubidar and Spanish dudar, Old Spanish dubdar.[7][6][5]

The Latin verb is a frequentative of dubō, recorded only in a gloss, itself from an adjective *dubos “in doubt”, beside dubius (“hesitant, doubtful”).[8][9] De Vaan takes the starting point to be “of two forms, double”, from the root of duo (“two”), and Wiktionary derives it from Proto-Indo-European *dwi- (“two-”) with *bʰuH- (“to be”).[9][1]

Earliest recorded meaning

In Lapa's glossary of the cantigas d'escarnho, Johan Baveca writes digu' eu verdad', esto non duvidedes “I tell the truth, do not doubt it”.[10] Another cantiga has quen dovidaria / que non tiredes gran prol “who would doubt that you will not draw great profit”.[11]

Semantic evolution

Besides “to be uncertain, disbelieve”, the older language used the verb for “to fear” and “to shrink from, refuse”: Morais (1789) gives receyar “to fear” as a sense, and Morais (1813) explains não duvidou a empreza as “he did not refuse the enterprise”.[12][13] Vieira quotes an old text on knights who must not hesitate to die for their natural lord, nom duvidarem morrer por seu senhor natural.[14] Medieval Latin dubitare and Old French douter also meant “to fear”.[15][16]

Bluteau (1712–1728) defines it as “not to be certain of something”, the sense that has prevailed.[17] In São Paulo it can mean “to challenge, dare”, and in Rio Grande do Sul it has the same uses as dudar from Spanish.[18][19]
