In theatre, a monologue (from Greek μονόλογος from μόνος mónos, “alone, solitary” and λόγος lógos, “speech”) is presented by a single character, most often to express their mental thoughts aloud, though sometimes also to directly address another character or the audience. Monologues are common across the range of dramatic media (plays, films, etc.), as well as in non-dramatic media such as poetry. Monologues share much in common with several other literary devices including soliloquies, apostrophes, and aside. There are, however, distinctions between each of these devices.
