Go in for accountancy? (5)
I believe the answer is:
enter
'go in' is the definition.
(as in entering a building)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for enter that I've seen before include "Gain access to" , "Break in" , "Enroll, sign up" , "Record - stage direction - come in" , "A key on the right" .)
