Get on a bit with work (6)
I believe the answer is:
obtain
'get' is the definition.
(I know that get can be written as obtain)
'on a bit with work' is the wordplay.
'on a bit' anagrams to 'OBTAIN'.
But, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for obtain that I've seen before include "Get one's hands on" , "Get or lay hold of" , "Get or receive" , "Hold good" , "Gain possession of" .)
