Gets in a tangle and growls angrily (6)
I believe the answer is:
snarls
'growls angrily' is the definition.
'snarls' can be an answer for 'growls' (I've seen this in another clue). I'm not certain of the 'angrily' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for snarls that I've seen before include "Growls of an angry dog" , "Growls angrily with bared teeth" , "Growls angrily, or tangles" , "Growls fiercely or tangles up" .)
