Think again about scattering paper on hike (10)
I believe the answer is:
reappraise
'think again about' is the definition.
I can't judge whether this definition defines the answer.
'scattering paper on hike' is the wordplay.
'scattering' indicates an anagram.
'on' indicates putting letters inside.
'hike' becomes 'raise' (synonyms).
'paper' with letters rearranged gives 'eappr'.
'eappr' placed within 'raise' is 'REAPPRAISE'.
Can you help me to learn more?
(Another definition for reappraise that I've seen is " From judge again".)
