Person who chatters, like bishop cracking joke (6)
I believe the answer is:
gasbag
'person who chatters' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'like bishop cracking joke' is the wordplay.
'like' becomes 'as'.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'cracking' means one lot of letters goes inside another (inserted letters go into a gap or crack).
'joke' becomes 'gag' (a gag is a joke or witticism).
'as'+'b'='asb'
'asb' placed within 'gag' is 'GASBAG'.
Can you help me to learn more?
(Other definitions for gasbag that I've seen before include "A compulsive talker with balloon?" , "a container of helium" , "One talking excessively" , "I talk too much" , "An informal blatherer" .)
