Loud group turning key - about time! (9)
I believe the answer is:
bombastic
'loud group turning' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'key about time' is the wordplay.
I cannot really understand how this works, but
'key' could be 'c' (musical key) and 'c' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'time' could be 't' (abbreviation) and 't' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bombastic that I've seen before include "High-flown" , "affected" , "Bimbo acts in boastful way" , "Pretentious" , "Declamatory, ostentatiously lofty" .)
