Promotion of short volume about friend and husband (8)
I believe the answer is:
ballyhoo
'promotion' is the definition.
(I know that ballyhoo is a type of promotion)
'short volume about friend and husband' is the wordplay.
'short volume' becomes 'boo' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'friend' becomes 'ally' (an ally is a friend or supporter).
'and' says to put letters next to each other.
'husband' becomes 'h' (abbreviation).
'ally'+'h'='allyh'
'boo' placed around 'allyh' is 'BALLYHOO'.
'of' is the link.
Can you help me to learn more?
(Other definitions for ballyhoo that I've seen before include "Extravagant publicity or fuss" , "Noisy or sensational publicity, hype" , "Exaggerated fuss" , "Hubbub" , "Brouhaha" .)
