Questions & Answers about Στο εστιατόριο η ατμόσφαιρα είναι πολύ ήσυχη απόψε.
Στο is the contracted form of σε + το.
So:
- σε = in / at / to
- το = the for a neuter noun
- στο = in the / at the / to the
In this sentence, στο εστιατόριο means in the restaurant.
This contraction is completely normal in Modern Greek and is usually what you should expect to see:
- σε + το → στο
- σε + τη(ν) → στη(ν)
- σε + τα → στα
After σε, Greek normally uses the accusative case.
So in full form, this is:
- σε το εστιατόριο
The noun εστιατόριο is neuter singular, and for many neuter nouns, the nominative and accusative forms are the same. So even though it is accusative here, it still looks like εστιατόριο.
That is why nothing seems to change on the noun itself.
