L
Its name in English is el or occasionally ell (pronounced /ɛl/).
History
The letter L is derived ultimately from the Semitic crook or goad which stood for /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, represent 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 some southern dialects of Chinese.
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 /ɬ/) in Welsh, where it can appear in an initial position.
A palatal L (IPA /ʎ/) occurs in many languages, and is represented by GL in Italian, LL in certain varieties of Spanish, LH in Portuguese, and Ļ in Latvian.
In English writing, L is often silent in such words as walk or could (its presence modifies other letters' sounds, i.e. 'wak' might be more likely to be pronounced such that it would rhyme with 'back').
Codes for computing
Alternative representations of L
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) or an uppercase letter I(i). 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.
Capital I(i) can also be hard to distinguish from a lowercase l(L), as many fonts use a vertical bar for both of these characters.
