Note strain finding hubby's lover? (8)
I believe the answer is:
mistress
'hubby's lover?' is the definition.
'mistress' can be an answer for 'lover?' (I've seen this before). I am not certain of the 'hubby's' bit.
'note strain' is the wordplay.
'note' becomes 'mi' (as in 'do re mi').
'strain' becomes 'stress' (synonyms).
'mi'+'stress'='MISTRESS'
'finding' acts as a link.
Can you help me to learn more?
(Other definitions for mistress that I've seen before include "Female teacher" , "Quickly, maybe" , "Lady" , "Female owner of a dog" , "she wears the trousers?" .)
