Twitter and tweeter (4)
I believe the answer is:
chat
This clue might be a double definition.
'twitter' is the first definition.
(thesaurus)
'tweeter' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for chat that I've seen before include "Talk easily; songbird" , "Talk amiably - bird" , "Talk informally; bird" , "Exchange text or voice messages through a computer" , "Talk casually" .)
