Imply that they're very close (8)
I believe the answer is:
intimate
This could be a double definition.
'imply that' is the first definition.
'intimate' can be an answer for 'imply' (I've seen this in another clue). I'm not sure about the remainder of the definition.
'very close' is the second definition.
(I've seen this in another clue)
'they're' is the link.
Can you help me to learn more?
(Other definitions for intimate that I've seen before include "Thick" , "Infer; personal" , "Make known" , "Familiar; imply" , "Close acquaintance" .)
