The study of the origins and meanings of names.
Onomatology helps researchers understand the historical significance of names in different cultures.
Onomatology is formed from "onoma" (ὄνομα) (meaning name) and "-logy" (from Greek "logia", meaning study or discourse). The word refers to the study of names and naming conventions.
Think of 'onoma' meaning 'name' and '-logy' meaning 'study' — so onomatology is the study of names.
