Most of celebrity magazine's awful (4)
I believe the answer is:
hell
'most of celebrity magazine's awful' is the definition.
I can't judge whether this definition defines the answer.
'most of celebrity magazine's' is the wordplay.
'most of' means to remove the last letter.
'celebrity magazine' becomes 'hello' (Hello is a celebrity magazine).
'hello' with its last letter taken away is 'HELL'.
Can you help me to learn more?
(Other definitions for hell that I've seen before include "Abode of the forces of evil" , "Underworld" , "uproar" , "Inferno" , "Horrible situation" .)
