Pronunciation

  • /estuˈdjoso/, [es.t̪uˈð̞jo.so][1]

Forms

estudioso (feminine estudiosa, masculine plural estudiosos, feminine plural estudiosas)[1]

Etymology

It is borrowed from Latin studiōsus (“eager, zealous; studious”).[2][1][3] The BDELC lists it among the derivatives of estudio, which is from studium (“zeal, application”).[4] Wiktionary notes that it can be analysed as the noun with -oso.[1] The same Latin adjective gave Portuguese estudioso, Catalan estudiós, French studieux and Italian studioso.[5][6][7]

The Latin adjective is formed from the noun with the suffix -ōsus; the noun is from studeō (“to devote oneself to”).[8][1]

Earliest recorded meaning

The first record is in Alfonso X's General estoria, part IV (1280), which speaks of showing the leedor estudioso “studious reader” the arrangement of the Septuagint translators.[9][10] The BDELC dates it only about 1450.[4][11]

Semantic evolution

Covarrubias (1611) defines it as a lover of knowledge.[12] Autoridades (1732) gives the sense “devoted to study” and a second, Latin sense “careful, eager, diligent”, illustrated by Quevedo.[3] The Academy labelled the second sense figurative and obsolete from 1817, and the DLE still records it as disused.[13][2] As a noun it now means a scholar, a person who studies a subject in depth.[2][14]
