Etymology

Origin of penetrate

First recorded in 1520–30; from Latin penetrātus “entered the interior of,” past participle of penetrāre “to enter the interior of,” from penet-, variant stem of penitus “deep down” + -āre, infinitive verb suffix, with the vowel change and addition of -r- probably by analogy with intus “inside,” intrāre “to enter” ( enter ( def. ) )
