'acuminate-fruited' originates from two elements: Latin 'acuminatus' (from 'acuminare'/'acumen'), where 'acumin-' meant 'point, sharpness', and Latin/Old French 'fructus'/'fruit', where 'fruct-'/'fruit' meant 'fruit, produce'.

'acuminate' entered English from Latin 'acuminatus' (via Medieval Latin and later scholarly botanical Latin) while 'fruit' came into English via Old French 'fruit' from Latin 'fructus'; the compound descriptive form 'acuminate-fruited' developed in botanical English to describe fruit shape.

Initially 'acuminatus' meant 'sharpened' or 'pointed' in Latin, and 'fructus' meant 'fruit'; over time the combined botanical phrase evolved to specifically mean 'having pointed (tapering) fruits' in modern usage.
