Interrogative Sentence

An interrogative sentence is a sentence form used to ask a question or seek information. It should be distinguished from embedded questions and from requests phrased as imperatives or declaratives.

Quick answer

An interrogative sentence asks a question or requests information; direct interrogatives are conventionally written with a question mark.

Important caveats

Scope Boundary

Not every request is grammatically interrogative, and embedded or indirect questions can appear inside declarative sentences without taking direct-question word order.

Further guidance

Application

Use interrogative structure when the sentence directly asks for information; in writing, direct questions conventionally end with a question mark.

Core Rule

An interrogative sentence is a sentence used to ask a question or request information.

Practical Application

Use an interrogative sentence when the sentence directly asks for information; direct questions conventionally take a question mark. Distinguish that structure from an embedded question inside a declarative sentence and from requests phrased as imperatives.

Reader Check

Is the whole sentence itself a direct question, or is the question content embedded inside another sentence?

Worked Example

“Where is the archive?” is interrogative and takes a question mark. “Please tell me where the archive is.” contains question content but is not itself a direct interrogative.
