'human-worshipper' is a Modern English compound formed from 'human' + 'worshipper', where 'human' denotes 'a person' and 'worshipper' denotes 'one who gives worship'.

'human' comes into English via Old French/Latin ('humanus') and 'worshipper' derives from Old English 'weorðscipe' -> Middle English 'worship' plus agentive suffix '-er', combining in modern usage as the compound 'human-worshipper'.

Initially each element simply meant 'person' and 'one who worships'; over time the compound has been used to describe someone who excessively admires or idolizes people rather than objects or deities.
