Fruit's outside, awfully large one: half of pear inside (6,4)
I believe the answer is:
orange peel
'fruit's outside' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'awfully large one half of pear inside' is the wordplay.
'awfully' indicates anagramming the letters.
'half of' indicates taking half.
'inside' indicates putting letters inside.
'pear' cut in half is 'pe'.
'large'+'one'='largeone'
'largeone' anagrammed gives 'orangeel'.
'orangeel' enclosing 'pe' is 'ORANGE-PEEL'.
Can you help me to learn more?
(Other definitions for orange peel that I've seen before include "Rind often candied" , "Bit of fruit" , "Pithy stuff" .)
