Charges youngsters over ecstasy (5)
I believe the answer is:
lades
'charges' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their -s form.
Maybe you can see a link between them that I don't see?
'youngsters over ecstasy' is the wordplay.
'youngsters' becomes 'lads' (I've seen this before).
'over' is an insertion indicator.
'ecstasy' becomes 'e' (informal term for the drug).
'lads' going around 'e' is 'LADES'.
Can you help me to learn more?
(Another definition for lades that I've seen is " Loads".)
