Rocky ledge (5)
I believe the answer is:
cliff
'rocky ledge' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cliff that I've seen before include "A sheer rock-face" , "High, steep rock face" , "Sir - - Richard" , "Steep high rockface" , "A sheer rock face, in mountain or by sea" .)
