Nibble at some vegetarian food as you read (6)
I believe the answer is:
browse
'read' is the 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?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for browse that I've seen before include "Look through book in leisurely way" , "Leaf through (a book)" , "Graze - glance through a book, magazine etc" , "Peruse - graze" , "Look at sites 13 ac" .)
