'monologue-centered' originates from the combination of 'monologue' and 'centered'. 'Monologue' comes from Greek, specifically the word 'monologos', where 'mono-' meant 'single' and 'logos' meant 'speech'.

'Monologos' transformed into the French word 'monologue', and eventually became the modern English word 'monologue'. The suffix '-centered' was added to form 'monologue-centered'.

Initially, 'monologue' meant 'a single speech', and 'centered' meant 'focused on'. Together, they evolved to mean 'focused on a single speech or speaker'.
