Item on page, very small piece (8)
I believe the answer is:
particle
This could be a double definition.
'item on page' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'very small piece' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for particle that I've seen before include "Speck of matter" , "Minute piece of matter" , "Minute fragment" , "Scrap" , "Grain, tiny piece" .)
