Burly gent regularly seen on Goon Show, originally (8)
I believe the answer is:
heavyset
'burly' is the definition.
(thesaurus)
'gent regularly seen on goon show originally' is the wordplay.
'regularly seen' means one should take alternating letters.
'on' says to put letters next to each other.
'goon' becomes 'heavy' (I can't explain this - if you can you should believe this answer much more).
'originally' indicates taking the first letters.
The initial letter of 'show' is 's'.
The alternating letters of 'gent' are 'et'.
'heavy'+'s'='heavys'
'et' put after 'heavys' is 'HEAVYSET'.
Can you help me to learn more?
(Other definitions for heavyset that I've seen before include "Mesomorphic" , "Stocky in stature" .)
