Post on social media that's short and sweet (4)
I believe the answer is:
twee
'post on social media' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?
'that's short and sweet' is the wordplay.
'short' indicates taking the first letters.
'and' is a charade indicator (letters next to each other).
'sweet' becomes 'wee' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'that' is 't'.
't'+'wee'='TWEE'
Can you help me to learn more?
(Other definitions for twee that I've seen before include "Excessively sentimental" , "Overly sentimental or pretty" , "rather quaint" , "Overly precious" , "Excessively pretty" .)
