Lively movement can be a job! (8)
I believe the answer is:
activity
This clue could be a double definition.
'lively movement' is the first definition.
'activity' can be an answer for 'movement' (I've seen this before). I am not sure about the 'lively' bit.
'a job' is the second definition.
(thesaurus)
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for activity that I've seen before include "Occupation or exercise" , "Recreational pursuit" , "Pastime or bustle" , "Busy movement" , "Hobby, pastime" .)
