'agamid' originates from the scientific classification 'Agamidae', which is derived from the Greek word 'agamos', meaning 'unmarried' or 'solitary'.

'Agamidae' was adopted into scientific nomenclature to classify a family of lizards, eventually leading to the common term 'agamid' in English.

Initially, it referred to a specific family of lizards, and this meaning has remained consistent in modern usage.
