Chapter in short life story: they might fly over the pond for celebrity (3,6)
I believe the answer is:
big cheese
'celebrity' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?
'chapter in short life story they might fly over the pond' is the wordplay.
'chapter' becomes 'ch'.
'in' is an insertion indicator.
'short' means to remove the last letter.
'life story' becomes 'bio' (short for biography).
'they might fly over the pond' becomes 'geese' (geese often live near ponds).
'bio' with its final letter taken away is 'bi'.
'bi'+'geese'='bigeese'
'ch' going into 'bigeese' is 'BIG CHEESE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for big cheese that I've seen before include "Important person (slang)" , "Important chap" , "VIP" , "Notable" , "boss" .)
