Forms

estimar (first-person singular present estimo, first-person singular preterite estimei, past participle estimado)[1]

Etymology

It is borrowed from Latin aestimō (“to set a price on; to value; to judge”).[2][3][1] Houaiss calls it a semi-learned word, while Wiktionary treats it as a learned borrowing that displaced the inherited esmar.[2][1] Cunha glosses it “to assess, calculate”, dates it to the 14th century (Old Galician-Portuguese osmar in the 13th) and calls it the popular form of the same Latin verb.[3] Spanish estimar is likewise taken from Latin, while the old popular Old Spanish asmar comes from Vulgar Latin *adaestimō.[4][5]

The Latin verb had the Old Latin form aestumō, and its origin is uncertain.[6][1] The usual analysis as aes (“bronze”) with a second part meaning “cut” does not convince de Vaan; he finds a link with Proto-Indo-European *h₂eys- (“to seek”), seen in aeruscō (“to beg”), more likely.[6][1]

Earliest recorded meaning

Lorenzo's earliest record is a charter of 1264: estimarse a renda dese ãno a mandado de dous oméés bous “let that year's rent be assessed by order of two good men”.[7] A satirical cantiga of Roi Paez de Ribela uses it in the same sense of judging or reckoning: non poderá estimar ben / se x' este carne, se pescaz “he will not be able to tell well whether this is meat or fish”.[7]

Semantic evolution

The first sense, to set a value on, survives in “to estimate”.[8] Nascentes, after Pacheco Júnior, calls it the etymological meaning.[8][2] Bluteau's first gloss is already fazer caso, to make much of someone or something.[9] Morais in 1813 puts this sense first (estimo muito o amigo), then “to assess” and “to reckon with, fear”, as in estimar o perigo.[10] Figueiredo marks “to suppose, fearing” as old.[11]

From esteem the verb passed to affection between people and to the sense “to be glad of”, and in letters estimar expresses a wish for someone's welfare.[2][12] Sailors use it for working out a ship's position by reckoning, fazer a estima.[2][13]
