Questions & Answers about Ο εμβολιασμός έγινε χτες.
Ο is the definite article meaning the.
It appears as ο because εμβολιασμός is a masculine singular noun in the nominative case.
So:
- ο εμβολιασμός = the vaccination
Greek articles change according to gender, number, and case, unlike English the, which always stays the same.
εμβολιασμός means vaccination.
A learner may confuse it with εμβόλιο, but they are different:
- εμβολιασμός = vaccination (the process/event)
- εμβόλιο = vaccine (the shot/substance)
So this sentence is talking about the vaccination event, not the vaccine itself.
