The act of causing someone to become distempered or emotionally disturbed; creating disorder.
From distemper + -ing (present participle suffix). The -ing suffix derives from Old English and creates the continuous or progressive form of verbs.
The -ing form is one of English's most versatile creations—it can be a verb form ('he is distempering'), a noun ('distempering is annoying'), or even an adjective ('the distempering behavior').
