A group of related organisms or languages that is smaller than a family but larger than a genus or branch.

Subfamily → It is formed from "sub-" (meaning under or below) and "family" (from Latin "familia", meaning household or family). The word "subfamily" refers to a group that is a subdivision of a larger family, indicating a classification that is below the main family level.
Think of a group that is 'under' ('sub-') a larger family — that's what a subfamily is, a smaller division within a family.
