Pronunciation

  • /penˈsaɾ/, [pẽnˈsaɾ][1]

Forms

pensar (first-person singular present pienso, first-person singular preterite pensé, past participle pensado)[1] Old Spanish texts also spell it penssar; the DEMel records forms such as penso, pensaua and piensa.[2] The stressed /e/ becomes ie in the present (pienso, piensa, piense), an irregularity the Diccionario de Autoridades already noted.[3]

Etymology

It is inherited from Old Spanish pensar, inherited from Latin pēnsō (“to weigh carefully; to consider”), the frequentative of pendō (“to weigh; to pay”).[4][5][1][6][7] The Latin verb already had the figurative sense “to weigh in the mind, ponder”, and Corominas treats the Spanish verb as a semi-learned doublet of pesar “to weigh”, the popular outcome of the same Latin word.[8][4] García de Diego and Wiktionary also call this form semi-learned.[9][1] French has the same pair, French peser and French penser; the Latin source of the verbs meaning “to weigh” had already lost its /n/.[10]

The verb with the sense “to think” is shared by the Romance languages of the West: Portuguese pensar, Catalan pensar, Occitan pensar and Italian pensare.[8][11][1] In Medieval Latin pensare meant “to consider, weigh, notice” and “to discuss”, as well as “to dole out rations”.[12]

pendō goes back to *pendō and to the Indo-European root *(s)pend- (“to pull; to spin”).[1]

Earliest recorded meaning

The first record is in the Cantar de mio Cid (c. 1140, known from a 14th-century copy): „Allí piensan de aguijar, allí sueltan las riendas” “there they set about spurring on, there they slacken the reins”.[13][4] The Fazienda de Ultra Mar (c. 1200) says of Esau that „penso en so coraçon quel matase” “he thought in his heart that he would kill him”, and the Cortes of León of 1208, the first text not known only from a later copy, speak of „pensando el remedio” “considering the remedy”.[13]

Semantic evolution

In the prose of Alfonso X the verb means “to imagine, consider, reflect”, “to intend to do something” and “to take care of someone”, and the infinitive is used as a noun, los sos muy malos pensares “his very wicked thoughts” (1280).[14] From “to take care of someone” it passed to “to give food to animals”, first in the 14th-century Libro de la montería of Alfonso XI, and this verb gave the noun pienso “fodder”, recorded from the end of the 16th century.[8][4] García de Diego instead derives this sense of the verb from pienso, which he traces to Latin pensum “ration”, and the Academy's dictionaries of 1884 and 2001 list it as a separate verb.[15][16][17]

Covarrubias (1611) defined it as turning something over in the memory, tracing it to the Latin frequentative pensare, because whoever thinks “weighs” things.[18] The Academy's dictionary of 1817 lists the phrases pensar en lo excusado “to attempt the impossible”, dar en qué pensar “to give grounds for suspicion” and sin pensar “unexpectedly”.[19] Baralt complained in 1855 that educated usage had given the verb nearly all the senses of French penser.[20] In the Dominican Republic, Colombia and Ecuador pensar can mean “to remember someone”, and Malaret recorded pensar a in this sense in Colombia.[21][22]
