"Литературу" is a feminine word is used in the accusative case.
- Я изучаю литературу.
- Литературу какую?
Feminine adjectives in the accusative case have the endings -ую, -юю.
The ending "ий" have a masculine adjective in the accusative case (not only this case).
Я изучаю русский язык.
Я изучаю русскую литературу.
Asher98October 2019Thank you, it's such a helpful comment!
It's simply adjective-noun agreement, accusative, of the feminine "object", which in this instance is "Russian literature", i.e., "русскую литературу:.
you need to pay closer attention to grammar rules of Russian regarding "cases" and how "endings" of words that are masculine, feminine, or neuter "inflect" according to the (1) case, (2) number -- as there are a different set of rules regarding pluralization of words that are masculine, feminine, or neuter. But be happy: @ least in Russian, unlike French, you don't need to attach an "article" to every noun and, unlike English, you needn't try to determine whether a noun (or adjective-noun paring) (1) requires an article @ all and (2) if an article is required, should it be "definite" or "indefinite". -exRanger
