Communist group that gets you going (3,5)
I believe the answer is:
the trots
'gets you going' is the definition.
I can't tell whether this defines the answer.
'communist group' is the wordplay.
I cannot really understand how this works, but
'communist' could be 'trot' (short for Trotskyist) and 'trot' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Other definitions for the trots that I've seen before include "many movements in a short time?" , "Those on the Left" .)
