Modern type of coffee, right? (6)
I believe the answer is:
latter
'modern' is the definition.
(thesaurus)
'type of coffee right?' is the wordplay.
'type of coffee' becomes 'latte' (I've seen this before).
'right?' becomes 'r' (common abbreviation).
'latte'+'r'='LATTER'
(Other definitions for latter that I've seen before include "Nearer the end" , "Second-mentioned; recent" , "Rattle (anag.)" , "Concluding" , "Second of two choices" .)
