'prickly-fruited' originates from the combination of 'prickly' and 'fruited', where 'prickly' refers to having sharp points and 'fruited' refers to bearing fruit.

'prickly' comes from Middle English 'prikly', and 'fruited' is derived from the Old French 'fruit', which eventually became the modern English word 'fruit'.

Initially, 'prickly' meant 'having sharp points', and 'fruited' meant 'bearing fruit'. The combination retains these meanings in modern usage.
