Tears spilt embracing lines of stars (7)
I believe the answer is:
stellar
'of stars' is the definition.
(I've seen this before)
'tears spilt embracing lines' is the wordplay.
'spilt' indicates an anagram.
'embracing' is an insertion indicator.
'lines' becomes 'll' (I've seen this in other clues**).
'tears' with letters rearranged gives 'stear'.
'stear' going around 'll' is 'STELLAR'.
(Other definitions for stellar that I've seen before include "Wonderful" , "Astral" , "Exceptionally good" , "Relating to the stars" , "of celebrities" .)
