Over-sentimental message abridged (4)

I believe the answer is:

twee

'over-sentimental' is the definition.

'message abridged' is the wordplay.
'message' becomes 'tweet' (type of online message).
'abridged' means to remove the last letter.
'tweet' with its final letter taken off is 'TWEE'.

(Other definitions for twee that I've seen before include "Excessively pretty" , "Sentimentally sweet" , "Pretty-pretty" , "Overly precious" , "Overly sentimental or pretty" .)

I've seen this clue in The Telegraph.
