Translation:This History is for the fourth semester.
So, because the word Ιστορία has a capital it is translated as History, rather than story? It's a bit odd in everyday English to say 'this History' - does it mean a particular 'history' of someone? 'A history of Mussolini' for example? Or does it refer to specifc classic texts like the Histories of Herodotus?
It refers to the particular subject. Αυτή η Ιστορία είναι για το τέταρτο εξάμηνο means that "this particular subject of History (let's say modern history) is for the fourth semester." If it had not a capital letter, then it would be "this story is about the fourth semester".
Anyway, we can use it, as students. Obviously it is about a course of History. The History courses, as much as I know are separated to semesters that concern historical periods. So a student could use it.
Imagine a scene where a classmate of him/her is holding a book of History. Question: "Κάνετε αυτή την Ιστορία σ' αυτό το εξάμηνο;" Answer: "Η Ιστορία αυτή είναι για το τέταρτο εξάμηνο".
Something like this. The problem is that the word ιστορία can be written with the same meaning (History) with a lowercase initial, so it depends on the context to understand what is the meaning, History or story. Link: http://www.lexigram.gr/lex/enni/%CE%B9%CF%83%CF%84%CE%BF%CF%81%CE%AF%CE%B1#Hist0
Thanks to both for the replies. It's still a bit odd in English though, if you were holding the book you would say 'This history book...' and if you were talking about the course it would be 'This history course...' The addition of 'this' complicates the usage for us. But of course we're here to learn how Greek works, not the other way around! Thanks also for the lexigram link, useful site :-)
Both words in English have the same origin. They are Greek. From the Ancient Greek: https://en.wiktionary.org/wiki/%E1%BC%B1%CF%83%CF%84%CE%BF%CF%81%CE%AF%CE%B1#Ancient_Greek The "problem" is more likely in English, because the meaning is different. You cannot tell to somebody "I 'll tell you a history". That is a narration. Or can we? The aspiration of the Ancient Greek word passed as h to Latin and from there to English. The word "story" comes from the same root too, but passed to English after the Norman conquest. https://en.wiktionary.org/wiki/story
So the same word had followed a different itinerary. Strange!
