Questions & Answers about Ο επαγγελματίας δουλεύει προσεκτικά.

What does Ο mean at the beginning of the sentence?

Ο is the masculine singular definite article, so here it means the.

In this sentence:

• Ο = the
• επαγγελματίας = professional

So Ο επαγγελματίας means the professional.

A useful point: Greek articles change depending on gender, number, and case, unlike English the, which never changes.

Why is it Ο επαγγελματίας and not just επαγγελματίας?

Greek often uses the definite article more frequently than English does. So where English might say the professional works carefully, Greek naturally says Ο επαγγελματίας δουλεύει προσεκτικά.

If you remove the article and say just επαγγελματίας, it sounds less like a complete normal statement and more like:

• a label
• a headline
• or part of a different structure

In ordinary full sentences, using the article here is the most natural choice.

Is επαγγελματίας masculine, feminine, or both?
