Titillate Republican with depraved habit in China? (3,7)
I believe the answer is:
tea service
'china?' is the definition.
(I've seen this before)
'titillate republican with depraved habit' is the wordplay.
'titillate' becomes 'tease'.
'republican' becomes 'r' (abbreviation).
'with' is a charade indicator (letters next to each other).
'depraved habit' becomes 'vice'.
'tease'+'r'+'vice'='TEA-SERVICE'
'in' is the link.
(Other definitions for tea service that I've seen before include "China possibly" , "that may be brought to the table" , "crockery" , "Cups, saucers, plates, etc" , "China pieces" .)
