L, or l, is the twelfth Letter (alphabet), letter of the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is English alphabet#Letter names, ''el'' (pronounced ), plural ''els''.

History

Lamedh may have come from a pictogram of an ox goad or cattle prod. Some have suggested that it represents a shepherd's staff.

Typographic variants

In most sans-serif typefaces, the lowercase letter ''ell'' , written as the glyph , may be difficult to distinguish from the uppercase letter "eye" (written as the glyph ); in some serif typefaces, the glyph may be confused with the glyph , the digit ''1 (number), one''. To avoid such confusion, some newer computer fonts (such as Trebuchet MS) have a finial (typography), finial, a curve to the right at the bottom of the lowercase letter ''ell''. Other style variants are provided in script typefaces and display typefaces. All these variants of the letter are encoded in Unicode as or , allowing presentation to be chosen according to each context. For specialist mathematical and scientific use, there are a number of dedicated codepoints in the Mathematical Alphanumeric Symbols block. In the ''Romain du Roi'', where the ascenders of lowercase letters have symmetrical serifs at the top, has an extra serif to the left at the mean line to distinguish it from capital . Another means of reducing such confusion is to use symbol , which is a cursive, handwriting-style lowercase form of the letter "ell". In Japan and Korea, for example, this is the symbol for the Litre, liter. (The International Committee for Weights and Measures recommends using or for the liter, without specifying a typeface.) In Unicode, the cursive form is encoded as from the "Letterlike Symbols (Unicode block), letter-like symbols" block. Unicode encodes an explicit symbol as . The TeX syntax

\ell

renders it as

\ell

. In mathematical formulas, an italic form (') of the script ℓ is the norm.

Use in writing systems

English

In English orthography, usually represents the phoneme , which can have several sound values, depending on the speaker's accent, and whether it occurs before or after a vowel. In Received Pronunciation, the alveolar lateral approximant (the sound represented in International Phonetic Alphabet, IPA by lowercase ) occurs before a vowel, as in ''lip'' or ''blend'', while the velarized alveolar lateral approximant (IPA ) occurs in ''bell'' and ''milk''. This velarization does not occur in many European languages that use ; it is also a factor making the pronunciation of difficult for users of languages that lack or have different values for it, such as Japanese language, Japanese or some southern dialects of Chinese language, Chinese. A medical condition or speech impediment restricting the pronunciation of is known as lambdacism. In English orthography, is often silent in such words as ''walk'' or ''could'' (though its presence can modify the preceding vowel letter's value), and it is usually silent in such words as ''palm'' and ''psalm''; however, there is some regional variation. L is the Letter frequency, eleventh most frequently used letter in the English language.

Other languages

usually represents the sound or some other lateral consonant. Common digraphs include , which has a value identical to in English, but has the separate value voiceless alveolar lateral fricative (IPA ) in Welsh language, Welsh, where it can appear in an initial position. In Spanish, represents (, , , , or , depending on dialect). A palatal lateral approximant or palatal (IPA ) occurs in many languages, and is represented by in Italian language, Italian, in Spanish language, Spanish and Catalan language, Catalan, in Portuguese language, Portuguese, and in Latvian language, Latvian. In Turkish language, Turkish, generally represents , but represents before , , , or . In Washo language, Washo, lower-case represents a typical [l] sound, while upper-case represents a Voicelessness, voiceless [l̥] sound, a bit like double in Welsh language, Welsh.

Other systems

The International Phonetic Alphabet uses to represent the voiced alveolar lateral approximant and a small caps, small cap to represent the voiced velar lateral approximant.

Other uses

* The capital letter L is used as the currency sign for the Albanian lek and the Honduran lempira. It was often used, especially in handwriting, as the currency sign for the Italian lira. Historically, it was commonly used as a currency sign for the British pound sterling (to abbreviate the Latin , a pound, see £sd); in modern usage, it has been overtaken by the pound sign (£), which is based on

\mathfrak

, the blackletter form of the letter. In running text, its lower-case form (usually italics, italicised), ''l'', was more often seen. * The Roman numeral L represents the number 50 (number), 50. * In the International system of units, the liter (or litre) is abbreviated using a lower-case or , or an upper-case . The latter form is used to avoid the risk of confusion between the letter l (el) and the numeral 1 (one) (For ℓ, see #ℓ, above.) * In watchmaking, the ligne (a traditional French measure of length still used in the industry) is abbreviated using an upper-case L. * In chemistry, L is used as a symbol for the Avogadro constant.H.

Computing

The Latin letters and have Unicode encodings and . These are the same code points as those used in ASCII and ISO 8859. There are also precomposed character encodings for and with diacritics, for most of those listed #Related characters, above; the remainder are produced using combining diacritics. Variant forms of the letter have unique code points for specialist use: the Mathematical Alphanumeric Symbols, alphanumeric symbols set in mathematics and science, and halfwidth and fullwidth forms for legacy CJK characters, CJK font compatibility.
