Suggest getting close (8)
I believe the answer is:
intimate
This clue is a double definition.
'suggest' is the first definition.
(intimating is a kind of suggesting)
'close' is the second definition.
(similar in meaning)
'getting' is the link.
(Other definitions for intimate that I've seen before include "Closely acquainted" , "Personal - hint - friend" , "Suggest to trusted friend?" , "Private and personal like close acquaintanceship" , "state" .)
