Snaps the twigs (6)
I believe the answer is:
shoots
This clue could be a double definition.
'snaps' is the first definition.
('shoot' can be a synonym of 'snap')
'the twigs' is the second definition.
The answer and definition can be both plants as well as being plural nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for shoots that I've seen before include "Fires a missile" , "New growths or branches" , "New sproutings" , "photo sessions?" , "Fires at new branches" .)
