Snaps emerging branches (6)
I believe the answer is:
shoots
I believe this clue is a double definition.
'snaps' is the first definition.
('shoot' can be a synonym of 'snap')
'branches' is the second definition.
(I have seen 'New branches ' mean 'shoots' so perhaps 'branches' could also mean 'shoots')
'emerging' acts as a link.
(Other definitions for shoots that I've seen before include "New sproutings" , "Fires a missile" , "fires gun" , "Wounds; germinates" , "New growths or branches" .)
