'elliptic-fruited' is a Modern English compound formed from 'elliptic' and 'fruited'. 'elliptic' originates from Greek, specifically the word 'elleiptikos' (via medieval Latin/Old French), where the root 'elleipsis' meant 'a falling short' (used for the conic section 'ellipse'); 'fruit' originates from Old French, specifically the word 'fruit', from Latin 'fructus', where 'fructus' meant 'enjoyment, produce'.

'elliptic' entered English through medieval Latin and Old French forms before becoming the Modern English adjective 'elliptic'; 'fruit' came into English from Old French 'fruit' (Latin 'fructus'); the compound adjective 'elliptic-fruited' developed in Modern English botanical usage to describe plants that bear elliptic fruits.

Initially, 'elliptic' referred to the geometric shape (from Greek notions of 'ellipse') and 'fruit' to produce; over time the compound came to mean specifically 'bearing elliptic-shaped fruits' in botanical contexts.
