Attack with a stone? (5)
I believe the answer is:
onset
'attack with a stone?' is the definition.
(I've seen this before)
'attack with a stone?' is the wordplay.
'stone' can be anagrammed to 'ONSET'.
However, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for onset that I've seen before include "Cast stone in attack" , "Initial stage; attack" , "Start - opening moments" , "17 down [ASSAULT]" , "Beginning or early stages" .)
