Questions & Answers about Ο υπεύθυνος τμήματος μιλάει με τον κηδεμόνα.

Why does the sentence start with Ο?

Ο is the masculine singular nominative definite article, equivalent to the.

Here it goes with υπεύθυνος, so Ο υπεύθυνος means the person in charge / the responsible one.

Greek articles change for:

• gender
• number
• case

So ο tells you that υπεύθυνος is:

• masculine
• singular
• the subject of the sentence

Is υπεύθυνος an adjective or a noun here?

It is originally an adjective meaning responsible, but here it is being used like a noun.

So ο υπεύθυνος literally means the responsible one, but in normal English we would usually say:

• the person in charge
• the supervisor
• the head

Greek does this a lot: an adjective with an article can function as a noun.
