Pronunciation
- /immaˈduɾo/, [ĩm.maˈð̞u.ɾo][1]
Forms
inmaduro (feminine inmadura, masculine plural inmaduros, feminine plural inmaduras)[1] The Autoridades spells it immaduro, after the Latin.[2]
Etymology
Wiktionary treats it as a learned borrowing, borrowed from Latin immātūrus (“unripe, immature; untimely”), adapted to the form of maduro.[1] The Autoridades also derives it from the Latin adjective.[2] Alemany and the Spanish Wiktionary analyse it instead as formed from Spanish in- + maduro.[3][4]
That adjective is formed from Latin in- (“not”) + mātūrus (“ripe”).[5][1] Spanish also has the more Latin form inmaturo, which Corominas lists as a learned word beside the popular one.[6]
Earliest recorded meaning
The Diccionario de Autoridades (volume 4, 1734) defines immaduro as “not in season, or not ripe” and quotes a line from L. Argensola's Rimas: para quitalle la immadura vida “to take away his unripe life”.[2]
Semantic evolution
In the 19th century the word was felt to be obsolete: Salvá (1846) and the Academy's editions of 1869 and 1884 marked it as old and sent the reader to inmaturo.[7][8][9] In the 18th-century Americas the form recorded is inmaturo, as in Lima in 1791 (frutos inmaturos).[10] Today inmaduro is the usual word: the DLE defines it as not yet having reached maturity, and, of people, inexperienced.[11] Moliner and the Vox apply it to fruit, to projects not yet worked out, and to people without the maturity of their age; medical usage applies it to incomplete physical or mental development.[12][13][14]
Timeline

- 1846 – Salvá marks inmaduro as old, the same as inmaturo.[7]
