Learns one's no stay-at-home? (5,3)
I believe the answer is:
finds out
'learns' is the definition.
('find out' can be a synonym of 'learn')
'one's no stay-at-home?' is the wordplay.
I cannot really understand how this works, but
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is found within the answer.
'at' could be 'in' and 'in' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for finds out that I've seen is " Gets information about, discovers".)
