Room also rearranged for a bit of fun (5)
I believe the answer is:
salon
'room' is the definition.
(salon is a kind of room)
'also rearranged for a bit of fun' is the wordplay.
'rearranged' indicates anagramming the letters.
'for' says to put letters next to each other.
'a bit of fun' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'also' anagrammed gives 'salo'.
'salo'+'n'='SALON'
Can you help me to learn more?
(Other definitions for salon that I've seen before include "where cuts are commonplace" , "Hairdresser's shop" , "social event" , "Place of business for eg beautician" , "Loans out as a reception room" .)
