Questions & Answers about Αυτό το Σάββατο, αν δεν βρέχει, πάμε στην αγορά και μετά στο πάρκο.

Why is it Αυτό το Σάββατο?

Because Σάββατο is a neuter noun in Greek: το Σάββατο = Saturday.

So this Saturday becomes:

• αυτό = this (neuter form)
• το = the (neuter article)
• Σάββατο = Saturday

So Αυτό το Σάββατο literally looks like this the Saturday, which is the normal Greek pattern with demonstratives.

Also, time expressions like this Saturday, this week, that day are often used without a preposition in Greek.

What case is Αυτό το Σάββατο, and why is there no visible case ending change?

It is functioning as a time expression, which in Greek is often in the accusative.

But here you do not see a change because Σάββατο is neuter, and in the singular the nominative and accusative look the same:

• το Σάββατο = nominative
• το Σάββατο = accusative

A clearer comparison is with a feminine day:

• αυτή η Κυριακή = this Sunday as a subject
• αυτή την Κυριακή = this Sunday as a time expression

So in your sentence, the form is doing accusative-type work even though it looks unchanged.

Why is there no word for we in the sentence?
