Clause type associated with questions
An interrogative clause is a clause whose form is typically associated with question like meanings. For instance, the English sentence "Is Hannah sick?" has interrogative syntax which distinguishes it from its declarative counterpart "Hannah is sick". Also, the additional question mark closing the statement assures that the reader is informed of the interrogative mood. Interrogative clauses may sometimes be embedded within a phrase, for example: "Paul knows who is sick", where the interrogative clause "who is sick" serves as complement of the embedding verb "know". Languages vary in how they form interrogatives. When a language has a dedicated interrogative inflectional form, it is often referred to as interrogative grammatical mood. Interrogative mood or other interrogative forms may be denoted by the glossing abbreviation .

Languages may use both syntax and prosody to distinguish interrogative sentences (which pose questions) from declarative sentences (which state propositions). Syntax refers to grammatical changes, such as changing word order or adding question words; prosody refers to changes in intonation while speaking. Some languages also mark interrogatives morphologically, i. e. by inflection of the verb. A given language may use one or more of these methods in combination.

Responses to questions are often reduced to elliptical sentences rather than full sentences, since in many cases only the information specially requested needs to be provided. (See Answer ellipsis.) Also many (but not all) languages have words that function like the English 'yes' and 'no', used to give short answers to yes–no questions. In languages that do not have words compared to English 'yes' and 'no', e. g. Chinese, speakers may need to answer the question according to the question. For example, when asked 喜歡喝茶嗎？ (Do you like tea? ), one has to answer 喜歡 (literally 'like') for affirmative or 不喜歡 (literally 'not like') for negative. But when asked 你打籃球嗎？ (Do you play basketball? ), one needs to answer 我打 (literally 'I play') for affirmative and 我不打 (literally 'I don't play') for negative. There is no simple answering word for 'yes' and 'no' in Chinese. One needs to answer the yes–no question using the main verb in the question instead. Responses to negative interrogative sentences can be problematic. In English, for example, the answer "No" to the question "You don't have a passport?" may confirm the negative, i. e. it means that the responder does not have a passport, but on the other hand, it can also imply that the responder does have a passport. Most often, a native speaker would also state an indicative sentence for clarification, i. e. "No, I don't have a passport," or even "No, I do have a passport," the latter most likely being used if the question were phrased, "Do you not have a passport?" which would connote serious doubt. However, in some other languages, such as Japanese, a negative answer to a negative question asserts the affirmative – in this case that the responder does have a passport. In English, "Yes" would most often assert the affirmative, though a simple, one word answer could still be unclear, while in some other languages it would confirm the negative without doubt. Some languages have different words for "yes" when used to assert an affirmative in response to a negative question or statement; for example the French si, the German doch, and Danish, Swedish or Norwegian jo. Ambiguity may also arise with choice questions. A question like "Do you like tea or coffee?" can be interpreted as a choice question, to be answered with either "tea" or "coffee"; or it can be interpreted as a yes–no question, to be answered "yes (I do like tea or coffee)" or "no (I do not like tea or coffee)".
