Move swiftly along to a profession (6)
I believe the answer is:
career
This might be a double definition.
'move swiftly' is the first definition.
(career can mean to race around)
'to a profession' is the second definition.
(someone's profession is their career or occupation)
'along' is the link.
I am not very happy about this link. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for career that I've seen before include "race" , "Not intellectual" , "'Occupation, profession (6)'" , "One's professional life" , "Run - profession" .)
