Star losing head: “get knotted!” (8)
I believe the answer is:
entangle
'star losing head get knotted' is the definition.
I can't tell whether this definition defines the answer.
'star losing head' is the wordplay.
'star' becomes 'pentangle' (I've seen this before).
'losing head' means to remove the first letter.
'pentangle' with its initial letter taken off is 'ENTANGLE'.
Can you help me to learn more?
(Other definitions for entangle that I've seen before include "snarl" , "Create confusion" , "Involve in complicated circumstances" , "Get all twisted up" , "Get tied up in knots in neat glen" .)
