Used one's head with striking effect (6)
I believe the answer is:
butted
'used' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Another definition for butted that I've seen is " Pushed or struck with head".)
I've seen this clue in the Evening Standard.
Want a hint initially instead of a full solution?
