Beluga, shortly cooked, causing waistline problem? (5)
I believe the answer is:
bulge
'waistline problem?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'beluga shortly cooked' is the wordplay.
'shortly' means to remove the last letter.
'cooked' indicates an anagram (letters cooked into a new form).
'beluga' with its final letter taken off is 'belug'.
'belug' with letters rearranged gives 'BULGE'.
'causing' is the link.
Can you help me to learn more?
(Other definitions for bulge that I've seen before include "Hump" , "Battle of the -----: last major German counter-offensive of WWII (1944)" , "Rounded swelling" , "Protuberance or outward swelling" , "Protrusion" .)
