Turns up retweet about drugs bill for smack (6)
I believe the answer is:
batter
'smack' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for batter that I've seen before include "Strike hard and often" , "Yorkshire pudding and cricket both require this" , "Strike violently and repeatedly" , "Cooking mix of flours, eggs and milk" , "Mixture for pancakes etc" .)
