Parcel yields I've corrupted, arriving outside normal times (7,8)
I believe the answer is:
special delivery
'arriving outside normal times' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'parcel yields i've corrupted' is the wordplay.
'corrupted' indicates anagramming the letters.
'parcel'+'yields'+'ive'='parcelyieldsive'
'parcelyieldsive' with letters rearranged gives 'SPECIAL DELIVERY'.
Can you help me to learn more?
(Other definitions for special delivery that I've seen before include "that a spinner hopes to produce?" , "What a courier may have brought" .)
