'unpersonified' originates from English, specifically the prefix 'un-' and the past participle 'personified' (from 'personify'), where 'un-' meant 'not' and 'personify' ultimately derives from Latin 'persona' meaning 'person' or 'mask'.

'unpersonified' was formed in modern English by combining the negative prefix 'un-' with the past participle 'personified' (itself from Old French/Latin roots such as Late Latin 'personificare' and Latin 'persona') and developed into the current adjective 'unpersonified'.

Initially, the elements meant 'not' + 'made into a person or given human characteristics'; over time the combined word has retained this sense of 'not given human form or human traits'.
