IPA: /ˌæl.əˈkjuː.ʃən/
KK: /ˌæl.əˈkjuː.ʃən/
A formal speech or address, often given in a serious or official context.
The judge delivered an allocution before sentencing the defendant.
Allocution is formed from "ad-" (meaning to) and "locutio" (from "loqui", meaning to speak). The word refers to a formal speech or address directed to a specific audience.
Think of someone 'speaking to' ('ad-' means to, and 'locutio' means to speak) an audience — that's what allocution means.
