Re-order punnet containing single salad item (4,3)
I believe the answer is:
pine nut
'salad item' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
're-order punnet containing single' is the wordplay.
're-order' is an anagram indicator (I've seen this in other clues).
'containing' is an insertion indicator.
'single' becomes 'I' (I as in one).
'punnet' with letters rearranged gives 'pnenut'.
'pnenut' enclosing 'i' is 'PINE NUT'.
Can you help me to learn more?
(Another definition for pine nut that I've seen is " Producer of evergreen".)
