Etymology

It is inherited from Latin pēnsō (“to weigh; to ponder”), which had come to mean “to think” in Late Latin.[2][3][1] The Latin verb is the frequentative of pendō (“to weigh, pay”), formed on the stem of its past participle; that verb goes back to Proto-Indo-European *(s)pend- (“to pull; to spin”).[2][4][1] Houaiss describes the Late Latin verb as taking over the senses of cōgitō (“to think”) and putō (“to reckon, think”): the first survives in a popular form meaning both “to think” and “to take care of”, the second only in learned derivatives such as putativo.[2]

Pesar “to weigh” is the popular continuation of the same Latin verb, and the two are doublets: Houaiss calls the verb for thinking the learned divergent form, and Carolina Michaëlis already called it divergent from the verb for weighing.[2][5][1] Corominas calls the Spanish verb semi-learned, from the idea of carefully weighing the pros and cons.[6] The same pair is Galician pensar and Galician pesar, Spanish pensar and Spanish pesar, French penser and French peser.[1][7]

The sense “to look after, tend; to dress (a wound)”, recorded from the 13th century, Houaiss explains from the long coexistence of the Late Latin verb with the Latin verb for “to think” that gave cuidar.[2] Nascentes had suggested the influence of that verb.[8] The same sense developed in Spanish, Catalan and French, where it was finally spelt apart as French panser.[2][9] The DLP instead gives this sense its own headword, formed from Portuguese penso + -ar.[10]

Earliest recorded meaning

In the cantigas the verb means “to reflect, to think of (someone or something)”, and pensar de “to take care of”.[5] In a cantiga d'amigo it means “to tend a wounded man”, and Gonçalo Anes do Vinhal writes que tam bem mandastes pensar “whom you had so well cared for”.[5][11] The Cantigas de Santa Maria use non é pensado for “it is unthinkable”, and the infinitive is already a noun, de que ei este pensar “why I have this thought”.[5][12]

Semantic evolution

Barbosa (1611) glosses pensar with cuydar and the Latin verbs for thinking and meditating.[13] Bluteau gives the proverb De vagar pensa, & obra depressa “think slowly and act quickly”, and the senses “to clean, swaddle and feed (a baby)” and “to feed and groom (a horse or mule)”.[14] Morais (1789) illustrates the mental sense with eu penso, logo existo, which he cites from Barros's Cartinha.[15][16] Vieira (1871–1874) splits the word into two articles, “to tend animals” and “to think”.[17]

Today the mental senses dominate;[2][10][18] “to dress a wound” and “to feed and groom animals” survive, and the DLP and Michaelis give them a separate entry.[2][10][18] In Trás-os-Montes pensar means “to feed (animals)”.[19]
