Tiles that see star, perhaps (7)
I believe the answer is:
'tiles' is the definition.
Although both the answer and definition are nouns, they are not in the same form of the noun.
'see star perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'seestar' with letters rearranged gives 'TESSERA'.
'that' is the link.
Can you help me to learn more?
(Other definitions for tessera that I've seen before include "Small square tile used in mosaics" , "Piece of picture" , "Die" , "Bit of mosaic" , "only part of the picture" .)
