Questions & Answers about Η καταστροφή έγινε σήμερα.
Η is the feminine singular form of the definite article, so here it means the.
It agrees with καταστροφή, which is a feminine singular noun. So:
- η καταστροφή = the disaster / the destruction
A native English speaker may notice that Greek articles change form depending on gender, number, and case, unlike English the, which always stays the same.
Because καταστροφή is:
- feminine
- singular
- here in the nominative case (because it is the subject of the sentence)
The nominative singular definite article for feminine nouns is η.
For comparison:
- ο = masculine singular nominative
- η = feminine singular nominative
- το = neuter singular nominative
So Greek is matching the article to the noun.
