Number one thing that stars do when out of whiskey (6)
I believe the answer is:
tinkle
'thing that stars do when out of whiskey' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'number one' is the wordplay.
I cannot really understand how this works, but
'number' could be 'l' (L is an example) and 'l' is found within the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tinkle that I've seen before include "A tiny toll" , "A short light ringing sound" , "Sound of a small bell" , "A series of short light ringing sounds" , "Make a light and clear ringing sound" .)
