Let fly see hooligan around tree (4,3)
I believe the answer is:
lash out
'let fly' is the definition.
Both the answer and definition are verbs in their base form.
Maybe there's an association between them I don't understand?
'hooligan around tree' is the wordplay.
'hooligan' becomes 'lout' (both can mean an aggressive person).
'around' is an insertion indicator.
'tree' becomes 'ash tree' (ash is a kind of tree).
'lout' enclosing 'ash' is 'LASH OUT'.
'see' is the link.
Can you help me to learn more?
(Other definitions for lash out that I've seen before include "Punch wildly" , "React aggressively" , "Attack with blows or words - using whip?" , "severely run down" , "Attack, verbally or physically" .)
