The question mark began as a medieval mark that used to signal rising intonation in texts

the gist

The question mark has a contested origin. A popular theory links it to a cat's tail, but Egyptian hieroglyphs had no punctuation. One explanation is that it came from the Latin word Quaestio, with its first and last letters stacked. From about 783, the Godescalc Evangelistary shows a diagonal squiggle, a lightning-flash shape later called the punctus interrogativus, which may have marked intonation. From the 10th century the sign was often used at the end of any clause, but in the early 13th century, as universities in Paris expanded book production, it was assigned specifically to questions. By 1598 the English term point of interrogation was recorded.

so what

Punctuation is a set of conventions that scribes and printers agreed on, not a fixed system, and the question mark took its modern meaning only after centuries of standardisation. Its history shows how writing evolved to carry the sound and tone of speech.

fun fact

The question mark has its own Unicode character, U+2E54 MEDIEVAL QUESTION MARK, for the old medieval form.
