'antique-minded' originates from Modern English compounding of 'antique' and 'minded'. 'antique' originates from Latin, specifically the word 'antiquus', where 'antiquus' meant 'ancient'.

'antique' entered English via Old French 'antique' (from Latin 'antiquus'); 'mind' comes from Old English 'gemynd' (memory, thought) and developed into the verb 'mind' and adjective/past-participle forms such as 'minded'. The compound 'antique-minded' was formed in Modern English by combining 'antique' + 'minded'.

Initially 'antique' meant 'of ancient times'; over time it also acquired the sense 'old-fashioned' or 'relating to antiques', and 'antique-minded' evolved to mean 'inclined toward antiques or old-fashioned ideas'.
