Questions & Answers about Αυτό το σχόλιο ήταν προσβολή.

Why is it αυτό and not αυτή or αυτός?

Because σχόλιο is a neuter singular noun, and the demonstrative αυτό has to agree with it in gender and number.

• masculine: αυτός
• feminine: αυτή
• neuter: αυτό

So:

• αυτός ο άνθρωπος
• αυτή η λέξη
• αυτό το σχόλιο

Greek agreement is much stricter than English here.

Why is there a το before σχόλιο?

Το is the definite article: the.

In Greek, when you use a demonstrative like αυτό before a noun, you normally also use the article:

• αυτό το σχόλιο = this comment
• εκείνο το σπίτι = that house

So Greek usually says literally something like this the comment, not just this comment without the article.

Is αυτό here a pronoun or an adjective?
