Syn.

– Indecorum is sometimes synonymous with indecency; but indecency, more frequently than indecorum, is applied to words or actions which refer to what nature and propriety require to be concealed or suppressed. Indecency is the stronger word; indecorum refers to any transgression of etiquette or civility, especially in public.
