Produce game, one wrapped in pink paper (5)
I believe the answer is:
fruit
'produce' is the definition.
(thesaurus)
'game one wrapped in pink paper' is the wordplay.
'game' becomes 'ru' (rugby union).
'one' becomes 'i' (Roman numeral).
'wrapped in' is an insertion indicator.
'pink paper' becomes 'ft'.
'ru'+'i'='rui'
'rui' inserted within 'ft' is 'FRUIT'.
(Other definitions for fruit that I've seen before include "Result - food" , "Seed-bearing growth" , "Eg, apple or pear" , "Reward of activity" , "Eg, bananas" .)
