Morphology

Trinitarian = Trinity (transparent) = trinity + arian

The adjective/noun is a straightforward derivation from 'Trinity' with the productive suffix '-arian' meaning 'relating to' or 'a person who supports/believes in'.

Etymology

Trinitarian comes from the Latin trinitas meaning 'three-ness' and the ending -arian meaning 'a person who follows or believes'. Think of tri- as in triangle or triple for 'three', so a Trinitarian is a person who believes that God is three persons.
