Make an assault with a zigzag movement, we hear (6)
I believe the answer is:
attack
'make' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for attack that I've seen before include "mount an offensive" , "Offensive or inslaught" , "Assault or criticise violently" , "Assault, offensive" , "Act violently against or criticise strongly" .)
