Questions & Answers about Η τελετή τελείωσε χτες.
Η is the definite article the for a feminine singular noun in the nominative case.
- η = feminine singular the
- ο = masculine singular the
- το = neuter singular the
The noun τελετή is feminine, so it takes η:

In this sentence, η τελετή is the subject, so the nominative form is used.
Τελετή is in the nominative singular, because it is the subject of the sentence: the ceremony is the thing that ended.
You can often identify the case by its role in the sentence:
- subject → usually nominative
- direct object → usually accusative
Here:
- Η τελετή = the subject
- τελείωσε = ended

So τελετή is nominative because it is the thing performing or undergoing the action of ending.
