Pronunciation

Forms

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

Etymology

It is borrowed from Latin aestimō (“to value, appraise; to esteem; to judge”).[2][3][4][1]

The popular descendant of a Vulgar Latin derivative, Vulgar Latin *adaestimō, was Old Spanish asmar “to think, judge” (aesmar in the Fuero Juzgo), very common in Old Spanish from the Cid to the early 15th century.[2] It has cognates in Portuguese esmar, Catalan esmar and Old French esmer.[5][1]

The Latin verb has an older form aestumō, of uncertain origin.[6][1] The old explanation from aes (“bronze, money”) and a word for “cut” is not convincing to de Vaan, who prefers a link with Proto-Indo-European *h₂eys- (“to seek”), the root of aeruscō (“to beg”).[6][1] Gómez de Silva still gives the derivation from the word for bronze as possible.[7]

Earliest recorded meaning

Corominas's first record is a Toledo glossary of about 1400, where it translates Latin aestimare.[2][3] The CDH has earlier records: a letter of Alfonso X of 1254 orders the keepers of the university to value the properties of the town por derecho aluguero “at a fair rent”, and the Aragonese Vidal Mayor (c. 1250) already has the participle estimada “valued”.[8] In the prose of Alfonso X it means both “to appraise, put a price on” and “to judge, believe”.[9]

Semantic evolution

Nebrija gives it as tassar, apreciar “to value, appraise”.[10] Covarrubias (1611) adds “to esteem, revere” and the phrases estimarse en mucho “to think highly of oneself” and estimarse en poco “to be humble”.[11] The Diccionario de Autoridades puts the price first and then the general sense of holding someone in esteem.[12] Today it also means to believe something from the available data, and in law to uphold a petition or appeal.[4]
