Sentence purpose and a classical text

In speech sentences serve four purposes: to report, to ask or find out, to command or urge, and to express a wish. By purpose of expression, declarative, interrogative, imperative and optative sentences are distinguished. A declarative sentence reports and usually ends with a full stop; an interrogative one ends with a question mark; an imperative one with a full stop or exclamation mark, and an optative one usually with a full stop or exclamation. The means that create these types are intonation, question words and particles (-mi, nima, qachon), and the imperative and optative mood forms of the predicate. One content can be said for different purposes: “Eshikni yop.” is a command, “Eshikni yopasanmi?” a question.
