Cry a little during the race (5)
I believe the answer is:
tweet
'cry' is the definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'a little during the race' is the wordplay.
'a little' becomes 'wee' (I've seen this in another clue).
'during' is an insertion indicator.
'the race' becomes 'tt'.
'wee' put into 'tt' is 'TWEET'.
Can you help me to learn more?
(Other definitions for tweet that I've seen before include "Chirrup" , "Short message on a social medium" , "Chirp of a small bird" , "Small bird's chirp" , "Bird noise" .)
