Crossword Genius

Resent a drunk getting sober (7)

Ross

I believe the answer is:

earnest

'sober' is the definition.
(thesaurus)

'resent a drunk' is the wordplay.
'drunk' indicates an anagram.
'resent'+'a'='resenta'
'resenta' with letters rearranged gives 'EARNEST'.

'getting' is the link.

(Other definitions for earnest that I've seen before include "Pledge - far from frivolous" , "Eager, sincere" , "Art deserving" , "art collector" , "Serious in intention" .)

I've seen this clue in The Telegraph.
