I understand the inclusion of the article but not 100% on why it is the accusative form of the article.
I would have thought the time it is the subject of the sentence and would have written it αυτή η φορά if left to my own devices.
I thought the same as well. My guess is that it's said with την because it's easier to separate the vowels. But I think you're still right.
You cannot just use the demonstrative pronoun αυτός/ή/ό without the definite article. It's just a language particularity... of the English language that it doesn't use it too! :P
Edit: To the contributors, if one of the two final ν's is needed, it's the other one: "Αυτήν τη φορά". I have to admit it looks a bit weird in the pronoun but that's how it should be; the second is optional, depending on when someone was at school (currently it's taught to be dropped).
The -ν of the fem. article τη(ν) and pronoun αυτή(ν) was always taught to be dropped. A recent adjustment was made concerning the masc. article τον.
Yes, I know what you mean now. To make matters worse I've just found that the rules for -ν are different in the primary and the junior high grammar books! It is to be dropped before τσ, τζ in primary but resurfaces when you're older apparently...
Funnily enough I said "she is wearing it" - I did see this sentence in the Adverbs section, so I understand why it's marked wrong initially, but is it not still technically correct?
Well, she is wearing it (when it is a feminine object like ζακέτα for example) is correct technically. :)
I always think of it as "this, the time" (like in The Godfather - "on this, the day of my daughter's wedding") and not "this, a time"
"η" is the nominative feminine definite article (i.e. "the"), so it would still be "This, the time", as you said. My question is why is it "την" (accusative) and not "η" (nominative).
Ah I misinterpreted you, sorry about that - I never really questioned it, but maybe it's to separate the vowel sounds. Much easier to say αυτή την than αυτή η. I know many languages insert a consonant for convenience like that, Greek included. Maybe a mod can confirm if that's the case here
