'diasporic' originates from modern English, formed from the noun 'diaspora' plus the adjectival suffix '-ic' meaning 'pertaining to'. 'Diaspora' itself comes from Greek 'διάσπορα' (diáspora).

'diasporic' developed from the English noun 'diaspora' (which entered English via Latin/French from Greek 'διάσπορα' meaning 'a scattering'); the adjective '-ic' was added in modern English to form 'diasporic' to describe things relating to a diaspora.

Initially the Greek term meant 'a scattering' (literally 'a sowing' or dispersion, used for seeds and people); over time its use narrowed and shifted to refer specifically to populations dispersed from a homeland, and 'diasporic' now means 'relating to such dispersion or its effects'.
