'wide-fruited' originates from Modern English, specifically from the combination of the adjective 'wide' (from Old English 'wīd') and 'fruited' formed from 'fruit' (ultimately from Old French 'fruit' and Latin 'fructus'), where 'wide' meant 'broad' and 'fructus/fruit' meant 'produce; fruit.'

'wide-fruited' developed as a compound adjective in post-medieval English by joining 'wide' + 'fruited' (with 'fruited' deriving from Middle English 'fruit' < Old French 'fruit' < Latin 'fructus'), and was later used in hyphenated form in botanical and descriptive contexts as 'wide-fruited'.

Initially the elements referred separately to 'broad' and 'fruit/produce'; over time the compound came to be used specifically to describe plants or varieties that bear fruits that are unusually wide in shape: 'having broad fruits.'
