Mobil loses barrels after China supplies refinery product (4,3)
I believe the answer is:
palm oil
'refinery product' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'mobil loses barrels after china' is the wordplay.
'loses' indicates named letters should be taken away.
'barrels' becomes 'b' (abbreviation).
'after' means one lot of letters go next to another.
'china' becomes 'pal' (I've seen this before).
'mobil' with 'b' taken out is 'moil'.
'moil' put after 'pal' is 'PALM-OIL'.
'supplies' acts as a link.
Can you help me to learn more?
(Other definitions for palm oil that I've seen before include "Vegetable fat" , "Fatty tree product" , "Product of tropical tree" .)
