Modern Standard Arabic (MSA) or Modern Written Arabic (MWA) is the variety of standardized, literary Arabic that developed in the Arab world in the late 19th and early 20th centuries, and in some usages also the variety of spoken Arabic that approximates this written standard. MSA is the language used in literature, academia, print and mass media, and law and legislation, though it is generally not spoken as a first language, similar to Contemporary Latin. It is a pluricentric standard language taught throughout the Arab world in formal education, differing significantly from many vernacular varieties of Arabic that are commonly spoken as mother tongues in the area; these are only partially mutually intelligible with both MSA and with each other depending on their proximity in the Arabic dialect continuum.
Many linguists consider MSA to be distinct from Classical Arabic (CA; اللغة العربية الفصحى التراثية al-Lughah al-ʻArabīyah al-Fuṣḥā at-Turāthīyah) – the written language prior to the mid-19th century – although there is no agreed moment at which CA turned into MSA. There are also no agreed set of linguistic criteria which distinguish CA from MSA; however, MSA differs most markedly in that it either synthesizes words from Arabic roots (such as سيارة car (Sayyārah) or باخرة steamship (Bākhirah)) or adapts words from foreign languages (such as ورشة workshop (Warshah) or إنترنت Internet (Inṭirnēt)) to describe industrial and post-industrial life.
