'shiny-fruited' originates from Modern English, specifically the adjective 'shiny' and the adjectival/past-participle form 'fruited' derived from 'fruit' + '-ed', where 'shiny' comes from 'shine' + '-y' meaning 'having the quality of shine' and 'fruited' means 'having fruit'.

'shiny' developed from Old English/Proto-Germanic roots of 'shine' (Old English scīnan -> Middle English shinen -> modern 'shine'), with the adjective-forming suffix '-y' producing 'shiny' in later English. 'Fruit' comes from Latin 'fructus' through Old French 'fruit' into Middle English 'fruit'; 'fruited' is formed in English by adding '-ed' to denote 'having fruit'. The compound 'shiny-fruited' is a modern English compound combining these elements.

Initially the elements meant 'having shine' and 'having fruit' separately; combined in modern usage they specifically describe plants or trees that bear glossy or lustrous fruit, a more focused descriptive sense.
