accentuate comes from Medieval Latin accentuātus, past participle of accentuāre ('to accent'), from Latin accentus ('intonation, accent'), from ad- ('to') + cantus ('song, singing'). Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the verb sense is "to make something more noticeable or prominent", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as accent, accented and derivatives such as accentuation, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin accentus, Latin cantus, which anchor the explanation in named linguistic material.
