Get all matted, but you have a brush (6)
I believe the answer is:
tangle
'brush' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
'get all matted but you have a' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tangle that I've seen before include "Twist, snarl, knot" , "coarse seaweed" , "Snarl or confused mass" , "Jumbled mass" , "Twist into a confused mass, say wool" .)
