Questions & Answers about Η έρευνα χρειάζεται ανάλυση.
Η is the feminine singular definite article, meaning the.
So:
- η έρευνα = the research
- η matches έρευνα because έρευνα is a feminine singular noun
It is capitalized here only because it is the first word of the sentence. In the middle of a sentence, it would be η.
Greek uses the definite article more often than English, so Greek may say η έρευνα even where English might simply say research.
Here έρευνα is in the nominative singular because it is the subject of the sentence: it is the thing that needs something.
So the structure is:
- Η έρευνα = the subject
- χρειάζεται = needs
- ανάλυση = the thing needed
A useful detail: έρευνα is one of those nouns whose nominative and accusative singular look the same as a bare noun:
- nominative: η έρευνα
- accusative: την έρευνα
The article changes, but the noun itself stays έρευνα.
