IPA: /ˈɪnɡrʌp/
KK: /ˈɪnˌɡrʌp/
A group of individuals who share common characteristics or interests, often seen as a social unit that distinguishes itself from others.
The ingroup often supports its members during difficult times.
Ingroup is formed from "in-" (meaning within) and "group" (from Old French *groupe*, meaning a collection or assembly). The word refers to a group of people who share common characteristics or interests and are considered as part of a collective.
Think of being 'within' ('in-') a 'collection' ('group') of people who share something in common.
