Soppy mouth attracting kiss from drunken lips? (7)
I believe the answer is:
mawkish
'soppy' is the definition.
(I've seen this before)
'mouth attracting kiss from drunken lips?' is the wordplay.
'mouth' becomes 'maw' (maw is a kind of mouth).
'attracting' is a charade indicator (letters next to each other).
'kiss from drunken lips?' becomes 'kish' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'maw'+'kish'='MAWKISH'
Can you help me to learn more?
(Other definitions for mawkish that I've seen before include "Effusively or insincerely emotional" , "Sentimental, schmaltzy" , "Soppy" , "Cloying" , "Sentimental in maudlin way" .)
