Pam made new plan (3)
I believe the answer is:
map
'new plan' is the definition.
'map' can be an answer for 'plan' (plan can mean a map of something). I'm not sure about the 'new' bit.
'pam made' is the wordplay.
'made' is an anagram indicator.
'pam' with letters rearranged gives 'MAP'.
Can you help me to learn more?
(Other definitions for map that I've seen before include "face" , "Travel guide" , "Chart" , "(Make a) geographical representation" , "Diagram of an area" .)
