Pronunciation

Forms

profundo (feminine profunda, masculine plural profundos, feminine plural profundas, superlative profundísimo)[1]

Etymology

It is a learned word, borrowed from Latin profundus (“deep”), and the learned doublet of the inherited hondo, which comes from the same Latin adjective or from its base.[2][3][1][4] The Latin word is formed prō- and fundus (“bottom”).[1][5] The noun goes back to Proto-Indo-European *bʰudʰmḗn.[1]

The popular outcome of the Latin adjective is Catalan pregon, through prevon.[4][6] The Old Occitan forms were preon and pregon, with dissimilation of the first syllable.[7] The Old French form was parfont, with a change of prefix, which was later remade as French profond after the Latin.[7][8] Corominas suggests that the inherited adjective itself comes from Old Spanish fondo, shortened from a dialect form perfondo of the second half of the 13th century, whose per- was taken for an intensive prefix.[2] Wiktionary instead derives the inherited adjective from the Latin noun used as an adjective.[1]

Earliest recorded meaning

The Fuero Juzgo (1254?) has the word in the figurative sense “hard to fathom, vast, penetrating”.[9][10] The BDELC dates the learned doublet to 1335.[2]

Semantic evolution

García de Diego calls profundo a cultismo, beside the inherited hondo.[4][2] Covarrubias (1611) defines it as what has great depth, such as el profundo del mar, and notes that it sometimes means “hidden, mysterious”.[11] The Diccionario de Autoridades already has most of the modern senses: deeper than usual, extended lengthwise (selva profunda), intense (profundo sueño), great (profunda erudición) and, of reverence, very humble.[12] The 1884 Academy dictionary adds what penetrates far, like roots or a wound, and what is hard to understand.[13]
