Cheers! That means I don't have to go to the doctor! (4,6)
I believe the answer is:
good health
'the doctor' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'cheers that means i don't have to go' is the wordplay.
I cannot really understand how this works, but
'cheers' could be 'health' and 'health' is present in the answer.
'go' is present in the answer.
The remaining letters 'od' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Another definition for good health that I've seen is " Cheers!".)
