Made of clay (7)
I believe the answer is:
earthen
'made of clay' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for earthen that I've seen before include "from the ground" , "Made of baked clay, perhaps ware" , "(Of pot) made of baked clay" , "Like many pots" , "that's thrown in clay" .)
