Etymology

[edit]

There are two primary theories of the origin of the question mark. One is that ⟨?⟩ descends from the punctus interrogativus , which instructed the reader (or singer) to raise the pitch of their voice while coming to a stop.

Another theory is that it derives from , an abbreviation of Latin quaestio (question), placed at the end of a question to mark it as such, and analogous to the derivation of ⟨!⟩.[1]

There are no documented intermediary forms to support one theory over the other.

Punctuation mark

[edit]

? (English name question mark)

  1. Used in various left-to-right scripts, including notably the Latin script, to mark the preceding sentence as a question.
  2. (comics, Internet slang) Used by itself to convey that the speaker is confused.
    Character #1: "I have no time to explain! Have you seen a Big Bad Wolf blowing down various houses?"
    Character #2: "?"
  3. (linguistics) Marks the following word or phrase as questionable for a grammatical or semantic-pragmatic reason.
    • 2006, Renaat Declerck, Susan Reed, Bert Cappelle, “The Grammar of the English Verb Phrase”, in The Grammar of the English Tense System, volume 1 (in English), →ISBN, page 6:
      A superscript question mark will be used similarly to indicate that a sentence or constituent is questionable for a grammatical or semantic-pragmatic reason. A double superscript question mark indicates an even higher degree of questionability.
      I have never { worked / ?been working } on a dissertation
      This time tomorrow I { will / ??am going to } be driving to London.
