Learner confused — oh, ask pro! Hurry! (4,5)
I believe the answer is:
look sharp
'hurry' is the definition.
('look sharp' can be a synonym of 'hurry')
'learner confused oh ask pro' is the wordplay.
'learner' becomes 'l'.
'confused' indicates an anagram.
'oh'+'ask'+'pro'='ohaskpro'
'ohaskpro' anagrammed gives 'ooksharp'.
'l'+'ooksharp'='LOOK SHARP'
(Other definitions for look sharp that I've seen before include "Get cracking" , "Get a move on" , "keen" , "step on it" , "Be quick!" .)
