It tastes better than a stick (6)
I believe the answer is:
carrot
This clue might be a double definition.
'it tastes better than' is the first definition.
The definition suggests a singular noun which matches the answer.
'a stick' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for carrot that I've seen before include "The vegetable for persuasion" , "Rewarding vegetable?" , "orangey colour" , "Incentive (but not the stick)" , "veg" .)
