[Grammar] Accusative Case
Welcome to your second of the 7 cases in Turkish. You have already been using the nominative case to describe subjects and some objects.
The accusative case in Turkish is used to mark specific direct objects. What does this mean exactly? A specific direct object is one that uses the article the. For example:
As you can see above, the accusative is only used when referring to the newspaper. General direct objects do not take the accusative or the plural suffix. Adding these to general direct objects in Turkish is simply not correct.
The accusative case is never used on subjects in Turkish. Do not translate every specific noun phrase with the accusative case. There is no way to distinguish between "a cat" and "the cat" when the subject of the sentence by using the accusative case. Only when they are direct objects is this possible.
Many languages have a Page that is stickied that simply provides links to all the individual grammar pages, so this page is accessed through the Turkish Grammar Portal. It would be nice though to have a link back to the main page. So here that is: https://www.duolingo.com/comment/7738932
