Questions & Answers about Αυτός ο μπελάς είναι σοβαρός.

Why does Greek use both Αυτός and ο before μπελάς?

This is a very common Greek pattern:

demonstrative + article + noun

So:

• Αυτός ο μπελάς = this trouble / this hassle

In English, we just say this trouble, but in Greek the article is normally kept.

A very literal breakdown would be:

• Αυτός = this
• ο = the
• μπελάς = trouble / hassle

Even though English does not say this the trouble, Greek does.

A second common word order is:

• ο μπελάς αυτός

This also means this trouble, but Αυτός ο μπελάς is the more basic pattern for learners.

What grammatical form is Αυτός here? Is it the same word as he?

Yes, it is the same basic word form, but here it is being used as a demonstrative adjective, not as a personal pronoun.

αυτός can mean:

• he when it stands alone
• this when it comes with a noun in patterns like αυτός ο...

So in this sentence:

• Αυτός ο μπελάς = this trouble

It does not mean he the trouble. The structure makes its function clear.
