When we begin a sentence with 'titles' like 'teamwork', facebook etc, do we need to put 'a' before them?
(A) Facebook is popular today among youngsters.'
(A)Teamwork is very important.
It is called as (a) group work.
When you mention about only Facebook being the one and only, is it not the same like the sun and internet. Both require 'the' to precede them, right? What about Facebook? Does it not require 'the' simply because it is like a proper name such as Daniel or something?
