Thinks about objects? (5)
I believe the answer is:
minds
This clue is a double definition.
'thinks about' is the first definition.
(minding is a kind of thinking about)
'objects?' is the second definition.
(to mind something is to object to it happening)
(Other definitions for minds that I've seen before include "Looks after for a while" , "Objects to; brains" , "Tends; objects to" , "Takes care of" , "Objects to; intellects" .)
