What one does under house arrest? It's the last part (4,7)
I believe the answer is:
home stretch
'part' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'what one does under house arrest? it's the last' is the wordplay.
I cannot really see how this works, but
'one' could be 'me' (a setter might use 'one' to humourously mean 'me') and 'me' is found in the answer.
'house' could be 'ho' (abbreviation for house) and 'ho' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'last' could be 't' (I've seen this in other clues) and 't' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' 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 home stretch that I've seen before include "final stage" , "Where the end is in sight" , "last stage of race" , "Final section of racecourse" , "It's almost the end" .)
