Forms

penetrar (first-person singular present penetro, first-person singular preterite penetré, past participle penetrado)[1]

Etymology

It is borrowed from Latin penetrō (“to put inside; to enter, penetrate”).[2][3][1] The Oxford Latin Dictionary connects the verb with penes (“in the power of”), with the ending of intrō (“to enter”).[4] De Vaan suggests it was formed to the adverb penitus (“from within, deeply”) on the model of the verb for “to enter” beside intus (“within”); both belong to penus (“food, provisions”), from Proto-Indo-European *pen-os (“food”).[5] Gómez de Silva and Bénaben also take the adverb from the noun, in the sense “innermost part of the house”, the family of the household gods, the Penates.[6][7] Covarrubias in 1611 already explained the verb as “to enter deep within”.[8]

Earliest recorded meaning

The first record is in the astrological Judizios de las estrellas of Alfonso X's court (1254–1260): corrompe se el ayre & penetra aquella quemazon “the air is corrupted and that burning penetrates”.[9][10] The Alfonsine dictionary reads it as “to make itself felt with violence”.[10] The BDELC dates the word only to the second quarter of the 15th century, and DICCA-XV reports the DCECH's date as 1440.[3][11]

Semantic evolution

Medical and poetic texts of the late 14th and early 15th centuries use the verb of water seeping through a vessel and of sight piercing the heavens.[9] Nebrija's Latin dictionary of 1492 glosses Latin penetro as entrar adentro “to go inside”.[11] Covarrubias adds the sense “to grasp what is hidden”, and calls a wound penetrante when it reaches a cavity.[8] The Diccionario de Autoridades distinguishes entering a body through its pores, passing through it (as the sun through glass) and making one's way into a place despite obstacles.[12] The Academy's 1843 edition added cold or shouts that make themselves felt, grief reaching the soul, and understanding someone's mind or a difficult matter.[13] The DLE now also records the sense “to possess sexually”.[2] Judeo-Spanish has penetrar and penetrarse “to study thoroughly”.[14]
