Embedded, as tiles (6)
I believe the answer is:
inlaid
'embedded as tiles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for inlaid that I've seen before include "Chased" , "(Of gems) embedded" , "Decorated with embedded elements" , "Set into surface ornamentally" , "Set in surface, perhaps a design" .)
