Message lovely and short in the end (5)

I believe the answer is:

'message' is the definition.
(type of online message)

'lovely and short in the end' is the wordplay.
'lovely' becomes 'twee' (twee can mean cute or lovely).
'and' means one lot of letters go next to another.
'in the end' suggests the final letters.
The last letter of 'short' is 't'.
'twee'+'t'='TWEET'

(Other definitions for tweet that I've seen before include "throwaway message?" , "Message from Trump?" , "Short online message" , "Short message posted on the internet" , "Note of a small bird" .)

I've seen this clue in The Times.
