Turgid Tom is a BBC fan (9)
I believe the answer is:
bombastic
'turgid' is the definition.
(synonyms)
'tom is a bbc fan' is the wordplay.
'fan' indicates an anagram (I've seen 'fanned' mean this (I've seen this in other clues)).
'tom'+'is'+'a'+'bbc'='tomisabbc'
'tomisabbc' with letters rearranged gives 'BOMBASTIC'.
(Other definitions for bombastic that I've seen before include "High-flown" , "Pompous -- inflated" , "Declamatory, ostentatiously lofty" , "affected" , "Extravagant" .)
