Angler quit Don, ludicrous and bombastic (13)
I believe the answer is:
grandiloquent
'bombastic' is the definition.
(I've seen this before)
'angler quit don ludicrous' is the wordplay.
'ludicrous' is an anagram indicator (a ludicrous spelling).
'angler'+'quit'+'don'='anglerquitdon'
'anglerquitdon' anagrammed gives 'GRANDILOQUENT'.
'and' acts as a link.
(Other definitions for grandiloquent that I've seen before include "Extravagant in style" , "Pompous in speech" , "Bombastic" , "Portentous" , "Self-important" .)
