Find a tiny amount (5)
I believe the answer is:
trace
I believe this is a double definition.
'find' is the first definition.
(I know that trace is a more specific form of the action find)
'a tiny amount' is the second definition.
(I've seen this in another clue)
(Other definitions for trace that I've seen before include "description of some elements?" , "Locate by investigation" , "indicator" , "Seek out" , "Copy; describe; draw" .)
