Q

Q is a letter of the Latin (Roman) alphabet, the script now used to write English and most languages of western Europe and, today, much of the world. It represents /k/ before /w/, almost always written 'qu'. Historically it is from Phoenician qoph by way of the Greek koppa, a letter Greek itself later dropped. Unlike the Hebrew and Greek alphabets, the Latin (Roman) alphabet never developed a systematic per-letter mystical or numerological tradition: Roman numerals form a separate, non-alphabetic system, so this entry stays with the letter's linguistic and historical record. The Roman alphabet is the youngest of the three historical scripts covered in this atlas: Latium adapted it around the 7th century BCE from a west Greek alphabet, reaching it through Etruscan intermediaries who had themselves taken their letters from Greek colonists settled in the bay of Naples. Latin calls each letter simply by its sound rather than by an inherited name, unlike Hebrew and Greek, and it never built an alphabetic numeral system of its own, so there is no ancient Latin counterpart to Hebrew gematria or Greek isopsephy; Roman numerals are a separate, non-alphabetic notation.

A modern practice called name numerology, drawn from a twentieth-century repeating 1-to-9 chart and commonly marketed as Pythagorean despite no documented link to Pythagoras, assigns the letter Q the digit 8; a rival popular scheme, the so-called Chaldean system, assigns different digits to the same letters, so even the two modern schemes disagree with each other.

The Latin Q's descent from Phoenician qoph, by way of a Greek letter called qoppa, is covered elsewhere in this atlas. Qoppa represented a sound classical Greek came to treat as redundant with kappa, and it dropped out of ordinary Greek writing, surviving only as the numeral symbol for ninety, a fate discussed alongside Greek isopsephy elsewhere. Latin kept the letter, however, because its makers needed it for a genuine Latin sound distinct from that of C or K, and Rome narrowed its use to a single context: Q appears in classical and modern Latin-derived spelling only followed by U, as in qu-, a restriction with no parallel among the other consonants carried over from Phoenician.

The Roman capital Q, a circle with a short descending tail, is essentially qoph's own ancient shape with that tail added, and the lowercase q, formed in medieval cursive by extending the tail into a full descender below the line, mirrors the lowercase p's ascender-free, descender-bearing structure on the opposite side of the alphabet. Q carries no Roman numeral value and, unlike I, V, X, L, C, D and M, was never pressed into any parallel notational system in classical Rome, remaining throughout its history a plain consonant letter with no numeral or gematria-style overlay.
