On about profession in lounge (7)
I believe the answer is:
recline
'lounge' is the definition.
(I've seen this before)
'on about profession' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'about profession' becomes 'cline' (I can't explain this - if you can you should believe this answer much more).
're'+'cline'='RECLINE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for recline that I've seen before include "Lean back to rest" , "Lie back and relax" , "Be recumbent" , "Lounge" , "Lie on one's back" .)
