Control like a coach, talking… (5)
I believe the answer is:
wield
'control' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for wield that I've seen before include "exercise" , "Use (weapon, authority)" , "Brandish a weapon or exert power" , "Handle - manage" , "Hold and use (a weapon or tool)" .)
