L

Egyptian hieroglyph	Phoenician lamedh	Western Greek Lambda	Etruscan L	Latin L

Lamedh may have come from a pictogram of an ox goadorcattle prod. Some have suggested that is represents a shepherd's staff.^[2]

In most sans-serif typefaces, the lowercase letter ell ⟨l⟩, written l, may be difficult to distinguish from the uppercase letter "eye" ⟨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. In the blackletter type used in England until the seventeenth century,^[3][a] the letter L is written as the render ${\displaystyle {\mathfrak {L}}}$ .

Another means of reducing such confusion is to use symbol ℓ, which is a cursive, handwriting-style lowercase form of the letter "ell"; this form is seen in European road signs and advertisements. In Japan, for example, this is the symbol for the liter. (The International Committee for Weights and Measures recommends using Lorl for the liter,^[4] 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.^[5] 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. Sometimes seen in Web typography, a serif font for the lowercase letter ell, such as l, in otherwise sans-serif text was used.

InEnglish 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 [l]) occurs before a vowel, as in liporblend, while the velarized alveolar lateral approximant (IPA [ɫ]) 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 walkorcould (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.

⟨l⟩ usually represents the sound [l] 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 [ɬ]) in Welsh, where it can appear in an initial position. In Spanish, ⟨ll⟩ represents /ʎ/ ([ʎ], [j], [ʝ], [ɟʝ], or [ʃ], depending on dialect).

Apalatal lateral approximant or palatal ⟨l⟩ (IPA [ʎ]) occurs in many languages, and is represented by ⟨gli⟩inItalian, ⟨ll⟩inSpanish and Catalan, ⟨lh⟩inPortuguese, and ⟨ļ⟩inLatvian.

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

InWasho, lower-case ⟨l⟩ represents a typical [l] sound, while upper-case ⟨L⟩ represents a voiceless [l̥] sound, a bit like double ⟨ll⟩inWelsh.

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.

• 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.^[b]
