Searches for tiny amounts (6)
I believe the answer is:
traces
This could be a double definition.
'searches' is the first definition.
The definition and answer can be both related to thinking as well as being verbs in their -s form.
Perhaps you can see an association between them that I can't see?
'tiny amounts' is the second definition.
(I've seen this in another clue)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for traces that I've seen before include "Finds; signs" , "Kick these over to be insubordinate or reckless" , "Just detectable amounts" , "Signs in crates" , "Tracks down or outlines" .)
