Posted info on top — crazy to get all soppy (11)
I believe the answer is:
sentimental
'all soppy' is the definition.
'sentimental' can be an answer for 'soppy' (thesaurus). I am unsure of the 'all' bit.
'posted info on top crazy' is the wordplay.
'posted' becomes 'sent' ('send' can be a synonym of 'post').
'on top' indicates taking the first letters.
'crazy' becomes 'mental' (mentally ill).
The first letter of 'info' is 'i'.
'sent'+'i'+'mental'='SENTIMENTAL'
'to get' is the link.
Can you help me to learn more?
(Other definitions for sentimental that I've seen before include "Mawkish" , "With tender, nostalgic or sad feelings" , "pathetic" , "Evoking tender emotions" , "Appealing to emotion rather than actuality" .)
