Crossword Genius

Writer ringing about groom (5)

Ross

I believe the answer is:

preen

Here is my best explanation:

'groom' is the definition.
(thesaurus)

'writer ringing about' is the wordplay.
'writer' becomes 'pen' (I've seen this before).
'ringing' indicates putting letters inside.
'about' becomes 're' (regarding**).
'pen' placed around 're' is 'PREEN'.
