For example, fine writer is into beer (8)
I believe the answer is:
penalise
'for example fine' is the definition.
(fine meaning penalise with money, parking fine say)
'writer is into beer' is the wordplay.
'writer' becomes 'pen' (something which writes).
'into' indicates putting letters inside.
'beer' becomes 'ale' (type of beer).
'is' inserted into 'ale' is 'alise'.
'pen'+'alise'='PENALISE'
(Other definitions for penalise that I've seen before include "See plain (anag.)" , "Disadvantage unfairly" , "Perhaps, fine" , "Inflict punishment on" .)
