Weathered point to odder shape (6)
I believe the answer is:
eroded
'weathered' is the definition.
(thesaurus)
'point to odder shape' is the wordplay.
'point' becomes 'e' (E is an example**).
'shape' indicates anagramming the letters.
'odder' with letters rearranged gives 'roded'.
'e'+'roded'='ERODED'
(Other definitions for eroded that I've seen before include "Wore away" , "Worn away, ground down" , "Worn away by weather or water" , "Eaten away" , "Worn away by time, wind or water" .)
