Big star making great din (3,5)
I believe the answer is:
red giant
'big star' is the definition.
(I've seen this before)
'making great din' is the wordplay.
'making' is an anagram indicator.
'great'+'din'='greatdin'
'greatdin' with letters rearranged gives 'RED GIANT'.
(Other definitions for red giant that I've seen before include "Large low-temperature star" , "Cool, immense star of high luminosity" , "Large, cool bright star" , "Huge Communist" , "Large star nearing the end of its life" .)
