KK: /ˈrɛtɪnu/
A group of people who accompany and serve an important person, often providing support or assistance.

Retinue → It is formed from 'retenue' (from Old French, meaning to retain or hold back) and the suffix '-e' (indicating a collective group). The word 'retinue' refers to a group of attendants or followers who are retained or held back by someone, typically a person of importance.
Think of a group of people who are 'held back' or 'retained' by someone important — that's what a retinue is, a collection of followers.
