Be quiet following work? That's a surprise (4)
I believe the answer is:
gosh
'work? that's a surprise' is the definition.
I can't judge whether this defines the answer.
'be quiet following' is the wordplay.
'be' becomes 'go' (going is a kind of being).
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'following' is a charade indicator (letters next to each other).
'go'+'sh'='GOSH'
Can you help me to learn more?
(Other definitions for gosh that I've seen before include "Crikey" , "Exclamation of surprise" , "My goodness!" , "Wow!" , "Well I never!" .)
