Part of the body produced by awful bad oilman (9)
I believe the answer is:
abdominal
'part of the body' is the definition.
Although both the answer and definition are adjectives, I can't understand how they can define each other.
'awful bad oilman' is the wordplay.
'awful' indicates anagramming the letters.
'bad'+'oilman'='badoilman'
'badoilman' anagrammed gives 'ABDOMINAL'.
'produced by' is the link.
Can you help me to learn more?
(Other definitions for abdominal that I've seen before include "Like stomachache" , "Stomachic" , "like tummy muscles" , "of part of body" , "Gutsy" .)
