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 Latinquaestiō(“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.
