Forms

cuidar (first-person singular present cuido, first-person singular preterite cuidei, past participle cuidado)[1] Medieval texts have coidar beside cuidar, and later coydar, cudar, cujdar and quidar.[2][3][4]

Etymology

It is inherited from Latin cōgitō (“to think, consider”), written Old Galician-Portuguese cuidar and Old Galician-Portuguese coidar in the oldest texts.[3][2][1] The Latin /g/ was lost and the diphthong ⟨oi⟩ then became ⟨ui⟩, which Nunes explains as metaphony.[5] Corominas traces the same steps in Spanish, from /koyedár/ to /koydár/ and /kuydár/.[6] The verb meant “to think”; since one thinks about what one pays attention to, it came to mean “to look after”.[7][2]

The same Latin word is Galician coidar, Spanish cuidar, Catalan cuidar, Old French cuidier (“to believe”) and Old Italian coitare.[8][1] cogitar is the learned doublet.[3][1]

The Latin verb is formed from con- and agitō (“to drive, stir”), from agō (“to drive”).[9][1][10]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century.[3][2] In the cantigas it means “to think, to judge” and “to brood, to grieve”, as in Afonso Mendez de Besteiros's que já per cuidar morrerei “for I shall die from brooding”; as a noun it means “opinion” in a meu cuidar “in my opinion”.[4][11]

Semantic evolution

Cardoso's dictionary of 1569 still translates cuidar by Latin opinor and cogito, “to think”.[12] Morais (1789) gives both “to have in mind” and “to take care of, watch over”, as in cuidar na saúde.[13] In the same way Spanish cuidar has its modern sense only from the 16th century.[14]

Today “to take care of” is the main sense, and “to think, to suppose” is literary or regional; dialect surveys in Portugal still record cuidar for “to judge, to think”.[3][1][15]

Timeline

  • 13th century – cuidar and coidar in the cantigas, meaning “to think”.[3][2][4]
