Rebate husband sorted out? Relax! (7)
I believe the answer is:
breathe
'relax' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'rebate husband sorted out?' is the wordplay.
'husband' becomes 'h'.
'sorted out?' indicates an anagram.
'rebate'+'h'='rebateh'
'rebateh' is an anagram of 'BREATHE'.
Can you help me to learn more?
(Other definitions for breathe that I've seen before include "Take inspiration" , "Gasp" , "Take in 30" , "wheeze" , "Expel gas" .)
