Does what's on all sides today for archers (7)
I believe the answer is:
quivers
'does' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for quivers that I've seen before include "Trembles" , "Cases for holding arrows" .)
