Intimate guys can love inside (7)
I believe the answer is:
mention
'intimate' is the definition.
(thesaurus)
'guys can love inside' is the wordplay.
'guys' becomes 'men'.
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'love' becomes 'o' (In tennis, 'love' means 'zero').
'inside' is an insertion indicator.
'tin' enclosing 'o' is 'tion'.
'men'+'tion'='MENTION'
(Other definitions for mention that I've seen before include "Passing reference" , "Allude to" , "Briefly refer to (something)" , "Make reference to" , "Speak of - refer to" .)
