Schmaltzy (7)
I believe the answer is:
mawkish
'schmaltzy' is the definition.
(I know that schmaltzy can be written as mawkish)
This is the entire clue.
(Other definitions for mawkish that I've seen before include "Insipid; maudlin" , "Effusively or insincerely emotional" , "Sentimental in maudlin way" , "Soppy" , "Sentimental, schmaltzy" .)
