Questions & Answers about Η προθεσμία ολοκλήρωσης είναι αύριο.

Why does the sentence start with Η?

Η is the feminine singular definite article, so it means the.

It matches προθεσμία, which is a feminine singular noun. So:

• Η προθεσμία = the deadline

Greek articles have to agree with the noun in gender, number, and case.

What is the grammatical role of προθεσμία here?

προθεσμία is the subject of the sentence, and it is in the nominative singular.

So the basic structure is:

• Η προθεσμία ολοκλήρωσης = the completion deadline
• είναι = is
• αύριο = tomorrow

Because προθεσμία is the thing being described, it appears in the nominative.

Why is ολοκλήρωσης in that form instead of ολοκλήρωση?
