fetishist

the word 'fetishist' is built upon the noun 'fetish', which entered english from portuguese 'feitiço', meaning a charm or object believed to have magical power. this portuguese term itself derives from latin 'factitius', meaning 'artificial' or 'made by art', which relates to the creation of such objects. the suffix '-ist', of greek origin via latin, is a common agentive suffix in english, used to form nouns indicating a person who practices or is concerned with something. thus, a 'fetishist' literally denotes a person concerned with or devoted to a fetish, with the meaning evolving from a focus on magical objects to a psychological or sexual fixation on specific objects or body parts.

Structure: fetish + ist fetish (from portuguese 'feitiço', meaning 'charm, sorcery', via latin 'factitius', meaning 'artificial') + ist (suffix of greek origin via latin '-ista', denoting an agent or person associated with a practice).
