Troublesome Naomi embraces learner, one in the fuel industry (6)
I believe the answer is:
oilman
'one in the fuel industry' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'troublesome naomi embraces learner' is the wordplay.
'troublesome' is an anagram indicator.
'embraces' means one lot of letters goes inside another.
'learner' becomes 'l'.
'naomi' is an anagram of 'oiman'.
'oiman' going around 'l' is 'OILMAN'.
Can you help me to learn more?
(Other definitions for oilman that I've seen before include "Owner of company that sinks wells for fuel" , "Person involved with crude" , "Worker" , "One working in the "black gold" industry" .)
