Forms

custar (first-person singular present custo, first-person singular preterite custei, past participle custado)[1] Old Galician-Portuguese wrote both custar and costar.[2][1]

Etymology

It is inherited from Vulgar Latin *cōstāre, from cōnstō (“to stand firm; to be established; to cost”), written Old Galician-Portuguese custar and Old Galician-Portuguese costar in the oldest texts.[2][1] The Latin verb is formed from con- (“together”) and stō (“to stand”), from Proto-Italic *komstaēō.[1] Houaiss notes that the sense “to have a price” is common to the Romance languages and seems to come from the Latin verb's use for what is known to be the case, completed by a statement of value or price.[2] The learned constar goes back to the same Latin word.[2][1]

The same Latin word is Galician custar, Spanish costar, Catalan costar, Occitan costar, French coûter and Italian costare;[3][1] Romanian custa means “to live”.[3][1] Nascentes explains the /u/ of the Portuguese verb from the older form with /o/, which was raised by metaphony in the forms stressed on the stem.[4]

Earliest recorded meaning

Lorenzo's chronology quotes a document of 1242–1252: custou o uino XXI soldos “the wine cost 21 soldos”.[5] In the Cantigas de Santa Maria a thing is had que lle non custasse nada “without its costing him anything”, and the Crónica Troiana has lle custou moy caro “it cost him very dear”.[5] The first sense is thus the price paid.[5]

Semantic evolution

Already in the medieval texts the verb applied to the price of an act as well as of a thing: in the Cantigas de Santa Maria a deed tanto lle custou “cost him so much” of his wealth, and a cantiga has custe o que custar “cost what it may”.[5][6] Bluteau (1712) defines it as being bought at a certain price.[7] Morais (1789) adds the senses of causing expense, toil or trouble, and custar a vida, to be the cause of someone's death.[8]

From “to cost effort” came “to be hard to do”, “to be painful” and “to be tiring”;[9] Brazilian Portuguese also uses it for being slow, taking long to happen.[2][9]
