To brag about being a great star (6)
I believe the answer is:
bogart
'a great star' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'to brag about' is the wordplay.
'about' is an anagram indicator.
'to'+'brag'='tobrag'
'tobrag' is an anagram of 'BOGART'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for bogart that I've seen before include "Humphrey --, US film actor" , "Lauren Bacall's first actor husband, d. 1957" , "Rob gat from the old film star" , "Famous player" , "American actor" .)
