Questions & Answers about Το κοινό ζητάει μπιζ.
Here το κοινό means the audience.
Literally, κοινό is an adjective meaning common or general, but it is also very commonly used as a noun: the public / the audience.
It is neuter singular because Greek often uses the singular for collective nouns. So even though an audience is made up of many people, Greek treats το κοινό as one group.
- το κοινό = the audience / the public
This is very natural Greek.
Greek uses the definite article much more often than English does.
So το κοινό is the normal way to say the audience. In this sentence, the speaker is referring to a specific audience, so the article is expected.
Compare:
- κοινό = audience/public in a more general or dictionary-like sense
- το κοινό = the audience
In real sentences, Greek usually prefers the full form with the article.
