IPA: /ˈhaɪpənɪm/
KK: /haɪˈpɒnɪm/
A word or phrase that is more specific than a general term, representing a particular instance or category within a broader category.
The word 'rose' is a hyponym of 'flower'.
Hyponym → It is formed from "hypo-" (from Greek "hypo", meaning under or below) and "onym" (from Greek "onuma", meaning name). A hyponym is a word that represents a specific instance of a broader category, thus being a name that is 'under' another name.
Think of 'hypo-' meaning 'under' and 'onym' meaning 'name' — a hyponym is a name that falls under a broader category.
