Don’t p@nic: Punctuation has rarely been truly stable

INTHEBEGINNINGWASTHEWORD, and the word was run together. Ancient texts (like the Greek of the Gospel of John) had few of the devices that tell readers where words begin and end (spaces), which words are proper names (the upper-lower case distinction), where breaks in meaning come (commas, dashes, semicolons and full stops), who said what (inverted commas), and so on.
Most people take punctuation to be something obvious and settled. In fact, the system is in a bit of upheaval.
