L is the twelfth letter of the Latin alphabet. Its name in English is el .

History

The letter L is derived ultimately from the Semitic (crook/goad) which stood for the phonetic value /l/. This originally may have been based on an Egyptian hieroglyph that was adapted by Semites for alphabetic purposes. The Greek letter Lambda Λ (upper case) or λ (lower case), as well as the equivalent Etruscan and Latin letters, have the same sound as the Semitic letter. In reference, it is spelled el or ell.

Pronunciation

In English, L can have several values, depending on whether it occurs before or after a vowel. The alveolar lateral approximant (the sound which the IPA uses the lowercase to represent) occurs before a vowel, as in lip or please, while the velarized alveolar lateral approximant (IPA ) occurs in bell and milk (see Dark L). This velarization does not occur in many European languages that use L; it is also a factor making the pronunciation of L difficult for users of languages that either lack, or have different values, for L, such as Japanese or Chinese. In English, L is often silent in such words as walk or calm.

L can occur before almost any plosive, fricative, or affricate in English. Common digraphs include LL, which has a value identical to L in English, but has the separate value voiceless alveolar lateral fricative (IPA ) in Welsh, where it can appear in an initial position.

A palatalised L (IPA ) occurs in many languages, and is represented by GL in Italian, LL in certain varieties of Spanish, LH in Portuguese, and Ļ in Latvian.

Codes for computing

In Unicode the capital L is codepoint U+004C and the lowercase l is U+006C. In some fonts, a lowercase l may be difficult to distinguish from a 1(one), a more stylized version based on the handwritten ℓ is sometimes used - this is often used as a suffix on a number to represent litres. Sometimes, capital I is also hard to distinguish from a lowercase l as well, as many fonts use a vertical bar for both of these characters. Its codepoint is U +2113 and its numeric character reference is "ℓ".

The ASCII code for capital L is 76 and for lowercase l is 108; or in binary 01001100 and 01101100, correspondingly.

The EBCDIC code for capital L is 211 and for lowercase l is 147.

The numeric character references in HTML and XML are "L" and "l" for upper and lower case respectively.
