Star and tiger entangled (3,5)
I believe the answer is:
red giant
'star' is the definition.
(I know that red giant is a type of star)
'and tiger entangled' is the wordplay.
'entangled' is an anagram indicator.
'and'+'tiger'='andtiger'
'andtiger' anagrammed gives 'RED GIANT'.
(Other definitions for red giant that I've seen before include "Large star nearing the end of its life" , "Huge Communist" , "big star" , "Megastar" , "Cool, immense star of high luminosity" .)
