This should get you going (8)
I believe the answer is:
laxative
'this should get you going' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for laxative that I've seen before include "Medicine for constipation" , "Aperient medicine" , "Purgative, loosener" .)
