Tell, “Close” (8)
I believe the answer is:
intimate
This clue is a double definition.
'tell' is the first definition.
(thesaurus)
'close' is the second definition.
(similar in meaning)
(Other definitions for intimate that I've seen before include "state" , "cosy" , "Infer; personal" , "Private and personal like close acquaintanceship" , "Personal - hint - friend" .)
