Trees uprooted and planted again (5)
I believe the answer is:
'and planted again' is the definition.
I can't tell whether this definition defines the answer.
'trees uprooted' is the wordplay.
'uprooted' indicates an anagram.
'trees' anagrammed gives 'RESET'.
Can you help me to learn more?
(Other definitions for reset that I've seen before include "Trees (anag)", "Changed reading", "Restore to required state", "Restore to the initial readings", "question that's appeared in exam again".)
