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.{{Cite web|url = http://www.ancient-hebrew.org/3_lam.html|title = Ancient Hebrew Research Center|access-date = 12 January 2015|archive-url = https://web.archive.org/web/20150103100530/http://www.ancient-hebrew.org/3_lam.html|archive-date = 3 January 2015|url-status = dead}}

In most sans-serif typefaces, the lowercase letter ell {{angbr|l}}, written as the glyph {{Sans-serif|{{char|l}}}}, may be difficult to distinguish from the uppercase letter "eye" {{angbr|I}} (written as the glyph {{Sans-serif|{{char|I}}}}); in some serif typefaces, the glyph {{Serif|{{char|l}}}} may be confused with the glyph {{char|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 {{unichar|004C}} or {{unichar|006C}}, 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, {{char|l}} has an extra serif to the left at the mean line to distinguish it from capital {{char|I}}.{{cite web|last=Kleinsorge|first=Moritz|url=https://www.identity-letters.com/blog/le-romain-du-roi|title=Le Romain du Roi|work=Identity Letters|access-date=9 January 2025}}

Another means of reducing such confusion is to use symbol {{char|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 {{char|{{serif|L}}}} or {{char|{{serif|l}}}} for the liter, without specifying a typeface.) In Unicode, the cursive form is encoded as {{Unichar|2113|SCRIPT SMALL L}} from the "letter-like symbols" block. Unicode encodes an explicit symbol as {{Unichar|1D4C1|MATHEMATICAL SCRIPT SMALL L}}.[https://www.unicode.org/versions/Unicode15.1.0/ch22.pdf The Unicode Standard, Version 15.0, Chapter 22] The TeX syntax $\backslash ell$ renders it as $\backslash ell$. In mathematical formulas, an italic form ({{char|ℓ}}) of the script ℓ is the norm.

In English orthography, {{angbr|l}} usually represents the phoneme {{IPAc-en|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 {{IPA|[l]}}) occurs before a vowel, as in lip or blend, while the velarized alveolar lateral approximant (IPA {{IPA|[ɫ]}}) occurs in bell and milk. This velarization does not occur in many European languages that use {{angbr|l}}; it is also a factor making the pronunciation of {{angbr|l}} difficult for users of languages that lack {{angbr|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 {{angbr|l}} is known as lambdacism.

In English orthography, {{angbr|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.

{{angbr|l}} usually represents the sound {{IPA|[l]}} or some other lateral consonant. Common digraphs include {{angbr|ll}}, which has a value identical to {{angbr|l}} in English, but has the separate value voiceless alveolar lateral fricative (IPA {{IPA|[ɬ]}}) in Welsh, where it can appear in an initial position. In Spanish, {{angbr|ll}} represents {{IPA|/ʎ/}} ({{IPA|[ʎ]}}, {{IPA|[j]}}, {{IPA|[ʝ]}}, {{IPA|[ɟʝ]}}, or {{IPA|[ʃ]}}, depending on dialect).

A palatal lateral approximant or palatal {{angbr|l}} (IPA {{IPA|[ʎ]}}) occurs in many languages, and is represented by {{angbr|gli}} in Italian, {{angbr|ll}} in Spanish and Catalan, {{angbr|lh}} in Portuguese, and {{angbr|ļ}} in Latvian.

In Turkish, {{angbr|l}} generally represents {{IPAslink|l}}, but represents {{IPAslink|ɫ}} before {{angbr|a}}, {{angbr|ı}}, {{angbr|o}}, or {{angbr|u}}.

In Washo, lower-case {{angbr|l}} represents a typical [l] sound, while upper-case {{angbr|L}} represents a voiceless [l̥] sound, a bit like double {{angbr|ll}} in Welsh.

The International Phonetic Alphabet uses {{angbr IPA|l}} to represent the voiced alveolar lateral approximant and a small cap {{angbr IPA|ʟ}} to represent the voiced velar lateral approximant.

{{main article|L (disambiguation)}}

• 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 {{lang|la|libra}}, a pound, see £sd); in modern usage, it has been overtaken by the pound sign (£), which is based on $\backslash mathfrak\{L\}$, the blackletter form of the letter. In running text, its lower-case form (usually italicised), l, was more often seen.{{efn|For example, see the Diary of Samuel Pepys for 31{{nbsp}}December 1661: " I suppose myself to be worth about 500l. clear in the world, ..."{{Cite book |last=Pepys |first=Samuel |title=The Diary of Samuel Pepys | chapter=Tuesday 31 December 1661 |date=31 December 2004 |chapter-url=https://www.pepysdiary.com/diary/1661/12/31/ |url-status=live |archive-url=https://web.archive.org/web/20211124225143/https://www.pepysdiary.com/diary/1661/12/31/ |archive-date=24 November 2021}}}}

• In the International system of units, the liter (or litre) is abbreviated using a lower-case {{char|l}} or {{char|ℓ}}, or an upper-case {{char|L}}. The latter form is used to avoid the risk of confusion between the letter l (el) and the numeral 1 (one) {{cite web|url=https://www.bipm.org/documents/20126/41483022/SI-Brochure-9-EN.pdf |title=The International System of Units (SI) {{!}} The SI brochure, 9th edition, 2019 |access-date=23 July 2023 |date=December 2022 |quote= {{serif|The litre, and the symbol lower-case l, were adopted by the CIPM in 1879 (PV, 1879, 41).

{{anchor|Codes for computing}}

The Latin letters {{angbr|L}} and {{angbr|l}} have Unicode encodings {{unichar|004C}} and {{unichar|006C}}. These are the same code points as those used in ASCII and ISO 8859. There are also precomposed character encodings for {{angbr|L}} and {{angbr|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.
