Lamedh

An iron cow-goad in the Israel Museum (lower right, 9th-7th century BC)

The letter is usually considered to have originated from the representation of an ox-goad, i.e. a cattle prod, or a shepherd's crook, i.e. a pastoral staff. In Proto-Semitic a goad was called *lamed-.[1][2]

The letter is named lām, and is written in several ways depending on its position in the word:

Some examples on its uses in Modern Standard Arabic. (Normally, diacritics are not written):

Lām is used as a prefix in two different ways. Lām-kasra (لـِ, /li/) is essentially a preposition meaning 'to' or 'for', as in لِوالدي liwālidī, 'for my father'. In this usage, it has become concatenated with other words to form new constructions often treated as independent words: for instance, لِماذا limāḏā, meaning 'why?', is derived from لـِ li and ماذا māḏā, meaning 'what?' thus getting 'for what?'. A semantically equivalent construction is found in most Romance languages, e.g. French pourquoi, Spanish por qué, and Italian perché (though ché is an archaism and not in current use).

The other construction, lām-fatḥa (لَـ /la/) is used as an emphatic particle in very formal Arabic and in certain fixed constructions, such as لَقد laqad (itself an emphatic particle for past-tense verbs) and in the conditional structure لو...لَـ law...la, effectively one of the forms of 'if...then...'.
