In a tangle (7)
I believe the answer is:
knotted
'in a tangle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for knotted that I've seen before include "Gnarled, knobbed" , "Tangled or tied fast" , "Interlaced; gnarled" , "Twisted" , "one's impolitely asked to get" .)
