Get into a brawl, initially being pushed around (6)
I believe the answer is:
obtain
'get' is the definition.
(I know that get can be written as obtain)
'into a brawl initially being pushed around' is the wordplay.
'initially' indicates taking the first letters.
'being pushed around' indicates an anagram.
The initial letter of 'brawl' is 'b'.
'into'+'a'+'b'='intoab'
'intoab' anagrammed gives 'OBTAIN'.
(Other definitions for obtain that I've seen before include "Hold good" , "Get, procure" , "Take possession of" , "Get or lay hold of" , "Acquire, secure" .)
