IPA: /ˈrɪŋˌliːdə/
KK: /ˈrɪŋˌlidər/
A person who leads a group, especially in activities that are not legal or are considered wrong.
The police arrested the ringleader of the gang after a long investigation.
Ringleader → It is formed from "ring" (from Old English "hring", meaning a circular band or circle) and "leader" (from Old English "lædere", meaning one who leads). The word "ringleader" refers to a person who leads a group, often in a conspiratorial or mischievous context, suggesting a central figure in a circle of participants.
Think of a 'ring' as a circle of people and a 'leader' as the one who guides them — a ringleader is the person at the center, directing the group.
