'anthologizer' originates from Modern English, specifically the verb 'anthologize' (formed from 'anthology' + the verb-forming suffix '-ize'), where 'anthology' ultimately comes from Greek 'anthologia' meaning 'a collection (literally a gathering of flowers)'.

'anthologizer' developed from Greek 'anthologia' → Late Latin/Old French forms (e.g. 'anthologie') → Modern English 'anthology' → verb 'anthologize' → agent noun 'anthologizer'.

Initially, the root 'anthologia' literally meant 'a gathering of flowers'; over time the sense shifted to 'a collection of literary pieces' and 'anthologizer' came to mean 'one who compiles such a collection'.
