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

History

Egyptian hieroglyph	Phoenician lamedh	Western Greek Lambda	Etruscan L	Latin L

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 ⟨l⟩, written as the glyph l, may be difficult to distinguish from the uppercase letter "eye" ⟨I⟩ (written as the glyph I); in some serif typefaces, the glyph l may be confused with the glyph 1, the digit one. To avoid such confusion, some newer computer fonts (such as Trebuchet MS) have a 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 U+004C L LATIN CAPITAL LETTER L or U+006C l LATIN SMALL LETTER L, 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.

Another means of reducing such confusion is to use symbol ℓ, which is a cursive, handwriting-style lowercase form of the letter "ell". In Japan and Korea, for example, this is the symbol for the liter. (The International Committee for Weights and Measures recommends using L or l for the liter, without specifying a typeface.) In Unicode, the cursive form is encoded as U+2113 ℓ SCRIPT SMALL L from the "letter-like symbols" block. Unicode encodes an explicit symbol as U+1D4C1 𝓁 MATHEMATICAL SCRIPT SMALL L. The TeX syntax <math>\ell</math> renders it as ${\displaystyle \ell }$. In mathematical formulas, an italic form (ℓ) of the script ℓ is the norm.

Use in writing systems

English

In English orthography, ⟨l⟩ usually represents the phoneme /l/, 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 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 ⟨l⟩; it is also a factor making the pronunciation of ⟨l⟩ difficult for users of languages that lack ⟨l⟩ or have different values for it, such as Japanese or some southern dialects of Chinese. A medical condition or speech impediment restricting the pronunciation of ⟨l⟩ is known as lambdacism.

In English orthography, ⟨l⟩ 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 eleventh most frequently used letter in the English language.

Other languages

⟨l⟩ usually represents the sound or some other lateral consonant. 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. In Spanish, ⟨ll⟩ represents /ʎ/ (, , , , or , depending on dialect).

A palatal lateral approximant or palatal ⟨l⟩ (IPA ) occurs in many languages, and is represented by ⟨gli⟩ in Italian, ⟨ll⟩ in Spanish and Catalan, ⟨lh⟩ in Portuguese, and ⟨ļ⟩ in Latvian.

In Turkish, ⟨l⟩ generally represents /l/, but represents /ɫ/ before ⟨a⟩, ⟨ı⟩, ⟨o⟩, or ⟨u⟩.

In Washo, lower-case ⟨l⟩ represents a typical sound, while upper-case ⟨L⟩ represents a voiceless sound, a bit like double ⟨ll⟩ in Welsh.

Other systems

The International Phonetic Alphabet uses ⟨l⟩ to represent the voiced alveolar lateral approximant and a small cap ⟨ʟ⟩ 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 libra, a pound, see £sd); in modern usage, it has been overtaken by the pound sign (£), which is based on the blackletter form of the letter. In running text, its lower-case form (usually italicised), l, was more often seen.
• The Roman numeral L represents the number 50.
• In the International system of units, the liter (or litre) is abbreviated using an upper-case (or a lower-case) L.
• 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.

Other representations

Computing

The Latin letters ⟨L⟩ and ⟨l⟩ have Unicode encodings U+004C L LATIN CAPITAL LETTER L and U+006C l LATIN SMALL LETTER L. These are the same code points as those used in ASCII and ISO 8859. There are also precomposed character encodings for ⟨L⟩ and ⟨l⟩ with diacritics, for most of those listed above; the remainder are produced using combining diacritics.

Variant forms of the letter have unique code points for specialist use: the alphanumeric symbols set in mathematics and science, and halfwidth and fullwidth forms for legacy CJK font compatibility.
