'bright-fruited' is a compound formed in English from 'bright' and 'fruit'. 'bright' ultimately comes from Old English 'beorht', where 'beorht' meant 'bright' or 'shining', and 'fruit' comes via Old French 'fruit' from Latin 'fructus', where 'fructus' meant 'fruit' or 'produce'.

'bright' developed from Old English 'beorht' into modern English 'bright', while 'fruit' came through Old French from Latin 'fructus'; the adjectival formation 'fruited' (having fruit) is formed by adding the past-participial/adjectival suffix '-ed' to 'fruit', yielding compounds like 'bright-fruited' in Modern English.

Initially the elements meant 'shining' (bright) and 'fruit' (produce), and when combined the compound came to be used descriptively for plants that bear conspicuously colored or shining fruit; the core idea has remained a literal description of fruit appearance.
