W

W 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 /w/. Historically it is a medieval addition, originally a ligature of two V or U letters ('double u'), created to write the Germanic /w/ sound that Latin V no longer supplied.

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 W the digit 5; 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.

Unlike every other letter in the modern Latin alphabet used in English, W was never part of the alphabet Rome used; it was invented in early medieval Britain and northern France to write the Germanic /w/ sound that classical Latin had no letter for. Old English scribes first represented that sound with the rune wynn, borrowed from the futhorc runic alphabet, but continental scribes writing Latin-alphabet texts more often doubled the letter U, or its angular twin V, writing uu or vv, a practice that gave the letter its name in English, double-u, still visible today in the French name for the same letter, double ve.

The doubled-V form gradually won out over wynn in English manuscripts by the late Middle Ages and was cast as a single ligated character by early printers, fixing W as a distinct letter of the alphabet by the time of the earliest English printing in the 15th century. Because W arrived so late, it took no part in the ancient Phoenician-to-Greek-to-Roman transmission covered for the alphabet's other letters, has no Roman numeral value, and never developed the kind of ancient mystical or numerological tradition that attaches to letters with a Semitic or Greek pedigree, since no ancient scribe or grammarian ever had reason to assign it a place in such a system.
