This might be a double definition.

'briefest bit' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'shuteye' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'of' is the link.

Can you help me to learn more?

(Other definitions for wink that I've seen before include "Lower eyelid briefly" , "Close eye briefly" , "Friendly eye movement" , "Sleep moment; twinkle" , "Convey an amused understanding" .)
