Change trees' layout (5)
I believe the answer is:
reset
'change trees' layout' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'trees' layout' is the wordplay.
'layout' indicates an anagram (an alternative layout of the letters).
'trees' anagrammed gives 'RESET'.
Can you help me to learn more?
(Other definitions for reset that I've seen before include "Replace, resettle or put back again" , "Adjust (eg clock, tuning)" , "Restore to original state" , "Put back to original state" , "Changed reading" .)
