He gets in the corn (7,5)
I believe the answer is:
harvest mouse
'corn' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'he gets in the' is the wordplay.
I cannot really see how this works, but
'he' could be 'harv' and 'harv' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for harvest mouse that I've seen before include "Smallest British rodent" , "rural resident" , "Cornfield rodent" .)
