Questions & Answers about Ο καταναλωτής ζητάει βοήθεια.
Ο is the masculine singular nominative definite article. In simple terms, it is the form of the that matches a masculine singular subject.
So:
- ο καταναλωτής = the consumer
Greek articles change according to gender, number, and case, so ο is used because καταναλωτής is:
- masculine
- singular
- the subject of the sentence
If you wanted a consumer, you would usually say ένας καταναλωτής.
Καταναλωτής is in the nominative case, which is the case normally used for the subject of the sentence.
You can tell this from both:
- the article: ο
- the role in the sentence: it is the one doing the action
So in Ο καταναλωτής ζητάει βοήθεια, the consumer is the one asking, so καταναλωτής is the subject.
A useful comparison:
- ο καταναλωτής = the consumer
- του καταναλωτή = of the consumer
That change from ο to του shows a change of case.
