Obese top celebrities: one accepting of his lot? (8)
I believe the answer is:
fatalist
'one accepting of his lot?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'obese top celebrities' is the wordplay.
'obese' becomes 'fat' (similar in meaning).
'top celebrities' becomes 'alist' (the A-list means very famous people).
'fat'+'alist'='FATALIST'
Can you help me to learn more?
(Other definitions for fatalist that I've seen before include "One believing in predetermination" , "Person who accepts life as it comes" , "philosophical type" , "One who accepts whatever happens as inevitable" , "One who accepts events as inevitable" .)
