A drop from the can? (3)
I believe the answer is:
oil
'a drop' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'from the can?' is the wordplay.
'from' becomes 'o' (I've seen this in other clues).
'the can?' becomes 'il' (I can't explain this - if you can you should believe this answer much more).
'o'+'il'='OIL'
Can you help me to learn more?
(Other definitions for oil that I've seen before include "Viscous substance for lubrication" , "what can be seen on iceberg" , "SECOND PART OF 23" , "Thick liquid that doesn't dissolve in water" , "What can be extracted" .)
