L

L 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 /l/. Historically it is from Phoenician lamed ('ox-goad') by way of Greek lambda. 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 L the digit 3; 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 L's descent in sound, from Phoenician lamedh through Greek lambda, appears elsewhere in this atlas. Graphically, lambda's sharp angle straightened in Etruscan and Roman hands into the simple right-angle L still used today, one of the more stable letterforms in the alphabet's history; the lowercase l is simply that same angle reduced to a single vertical stroke, among the plainest shapes in the Latin alphabet. Separately, L is one of seven Latin letters that also serves as a Roman numeral, standing for fifty.

Unlike I, V and X, which the standard account derives from tally notches, L's numeral value has no agreed derivation from its shape or sound: one common explanation holds that L is half of the older symbol used for one hundred, split along its vertical axis, though this is not settled with the same confidence as the tally-mark origin of the smaller numerals, and other reconstructions of the early Roman numeral system differ. Whatever its origin, the numeral use is a later, purely notational overlay on the letter and carries no relation to lamedh's Hebrew meaning of an ox-goad or to any gematria-style tradition covered elsewhere in this atlas for the Hebrew and Greek alphabets.
