Tool for moving sun tile (7)
I believe the answer is:
utensil
'tool' is the definition.
(thesaurus)
'moving sun tile' is the wordplay.
'moving' is an anagram indicator.
'sun'+'tile'='suntile'
'suntile' is an anagram of 'UTENSIL'.
'for' is the link.
(Other definitions for utensil that I've seen before include "one's employed in the kitchen" , "Implement, maybe in kitchen" , "Handy kitchen tool" , "Can opener, for example" , "Implement for practical use" .)
