'democratic-minded' originates from Modern English, specifically the combination of 'democratic' + 'minded'. 'democratic' ultimately comes from Greek 'dēmokratikos', where 'dēmos' meant 'people' and 'kratos' meant 'power', and 'minded' derives from 'mind' meaning a disposition or way of thinking.

'democratic' entered English via French/Latin forms from Greek 'dēmokratia' (rule of the people), later forming the adjective 'democratic' in Modern English; 'mind' comes from Old English 'gemynd'/'mynd' (memory, thought) which developed into the Modern English noun 'mind' and adjective-forming compounds like '-minded'. The compound 'democratic-minded' is a modern English formation combining these elements.

Initially 'democratic' referred specifically to matters of 'rule by the people' (dēmokratia), and 'mind(ed)' referred to mental disposition; over time 'democratic' broadened to describe support for democratic values and practices, and the compound 'democratic-minded' came to mean 'having a disposition toward democratic/equal participation or values'.
