Friend gets limo running on ingredient (4,3)
I believe the answer is:
palm oil
'ingredient' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'friend gets limo running' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'running' indicates an anagram (the letters run around to different places).
'limo' is an anagram of 'lmoi'.
'pal' going around 'lmoi' is 'PALM-OIL'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for palm oil that I've seen before include "Fatty tree product" , "Product of tropical tree" , "Vegetable fat" .)
