Pam's new plan (3)
I believe the answer is:
map
'plan' is the definition.
(I've seen this before)
'pam's new' is the wordplay.
'new' indicates an anagram.
'pam' with letters rearranged gives 'MAP'.
(Other definitions for map that I've seen before include "(Make a) geographical representation" , "Diagram of part of the earth's surface" , "Travel guide" , "Chart" , "Sketch" .)
