Lexicon

In the study of bilingualism, the lexical level of language is of prime importance because, in practical terms, vocabulary acquisition is an essential prerequisite for the development of skill in language use; from a theoretical point of view, the mental lexicon, as a bridge between form and meaning, plays a crucial role in any model of language processing.

The Arabic–English Lexicon is an Arabic-English dictionary complied by Edward William Lane (died 1876). It was published in eight volumes during the second half of the 19th century. It consists of Arabic words defined and explained in the English language. But Lane does not use his own knowledge of Arabic to give definitions to the words. Instead, the definitions are taken from older Arabic dictionaries, primarily medieval Arabic dictionaries. Lane translates these definitions into English, and he carefully notes which dictionaries are giving which definitions.
