Present participle of deprave; the ongoing act of making someone morally corrupt.
From deprave + -ing (present participle suffix). The -ing suffix comes from Old English and creates verbs showing continuous action or can function as nouns (gerunds).
The -ing form is one of English's superpowers—it can work as a verb ('he is depraving'), a noun ('depraving is wrong'), or an adjective ('a depraving influence'), all from the same ending.
