In grammar, a declarative sentence has the shape of a statement. It tells you something.

In grammar在文法裡， a declarative sentence has the shape of a statementdeclarative sentence（直述句）的形式就是一個陳述句。 It tells you something它是在告訴你某件事。

It is not asking (interrogative), not ordering (imperative), and not crying out (exclamative). “The door is open.” That is declarative. “Is the door open?” is not. Teachers use the word when they sort sentence types.

It is not asking (interrogative)它不是在問問題（interrogative，疑問句）， not ordering (imperative)不是在下命令（imperative，祈使句）， and not crying out (exclamative)也不是在驚嘆（exclamative，感嘆句）。 "The door is open." That is declarative.「The door is open.」這句就是declarative（直述句）； "Is the door open?" is not.「Is the door open?」則不是。 Teachers use the word when they sort sentence types老師在分類句子類型時會用到這個詞。

The tone can still be strong or soft; what matters is the form: it is built as a telling, usually with a subject and a verb in statement order. You can turn the same idea into a question by changing the form; the meaning is close, but the sentence type has changed.

The tone can still be strong or soft語氣仍然可以強烈或溫和； what matters is the form重要的是形式： it is built as a telling它是以「陳述」的方式構成的， usually with a subject and a verb in statement order通常主詞和動詞會按照陳述句的順序排列。 You can turn the same idea into a question by changing the form你可以改變形式，把同樣的意思變成問句； the meaning is close, but the sentence type has changed意思相近，但句子的類型已經改變了。

The word is mainly a classroom and linguistics word. Programmers also talk about “declarative” style (you say what you want, not every step), and that is a different neighbourhood of the same idea — stating rather than commanding — though actually that use is later and more specialist. The grammar sense is the one learners meet first.
