Show displeasure when things get tangled up (5)
I believe the answer is:
snarl
'show displeasure' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for snarl that I've seen before include "Say something aggressively" , "Growl in a threatening manner" , "Bare teeth and growl" , "Show one's teeth (like a lion)" , "A vicious angry growl" .)
