Communicate what means little, time after time (5)
I believe the answer is:
tweet
'communicate' is the definition.
(I've seen this before)
'little time after time' is the wordplay.
'little' becomes 'wee' (similar in meaning).
'time' becomes 't' (abbreviation).
'after' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'wee'+'t'='weet'
'weet' put after 't' is 'TWEET'.
'what means' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tweet that I've seen before include "Short message posted on the internet" , "online comment" , "Short message on a social medium" , "Short online message" , "Short message posted on a social network" .)
