Scriptio continua (Latin for "continuous script") is a style of writing that does not use spaces, different letter cases, or punctuation to tell apart words, phrases, or sentences. It was a common way of writing for texts in Ancient Greek and Classical Latin. Even though Greek and Latin speakers already created punctuation to tell words apart, "scriptio continua" was often used to save space. This was because writing materials were expensive and the boundaries between words, clauses, and sentences are not so clear in spoken language.
