Think of mirror (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
reflect
I believe this clue is a double definition.
'think of' is the first definition.
(thesaurus)
'mirror' is the second definition.
(thesaurus)
(Other definitions for reflect that I've seen before include "Think - send back" , "Ponder or produce an image" , "Display" , "Meditate - mirror - show" , "Think or mirror" .)
