'archetypist' originates from English, specifically from the noun 'archetype' + the agentive suffix '-ist'. 'Archetype' comes from Greek elements 'archē-' (beginning, first) and 'tupos' (impression, model).

'Archetype' entered English via Late Latin and French (French archétype) from Greek 'archetypos'; the agentive suffix '-ist' (from Greek/Latin via French) was later appended in English to form nouns meaning 'one who practices or is concerned with' (e.g., 'artist'); 'archetypist' is a modern English coinage built from these elements.

Initially 'archetype' meant 'first-molded impression' or 'original model' in Greek; over time it broadened to mean 'typical example' or 'recurring pattern' in modern usage. 'Archetypist' has come to mean either a maker/studier of such models or someone who exemplifies them.
