Spoke savagely when all tangled up (7)
I believe the answer is:
snarled
'spoke' is the definition.
(snarling is a kind of speaking)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for snarled that I've seen before include "In a twist - showed one's teeth" , "Knotted; growled" , "Growled or tangled in knots" .)
