Suggest getting close (8)
I believe the answer is:
intimate
I believe this is a double definition.
'suggest' is the first definition.
(synonyms)
'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" .)
