Pretty busy after a dry run (10)
I believe the answer is:
attractive
'pretty' is the definition.
(thesaurus)
'busy after a dry run' is the wordplay.
'busy' becomes 'active' (similar in meaning).
'after' is a charade indicator (letters next to each other).
'dry' becomes 'tt' (abbreviation for teetotal).
'run' becomes 'r' (cricket abbreviation).
'a'+'tt'+'r'='attr'
'active' put after 'attr' is 'ATTRACTIVE'.
(Other definitions for attractive that I've seen before include "Pleasing to the eye" , "Good-looking" , "Pleasant-looking" , "Fetching; cute" , "fascinating" .)
