Judeo-Arabic dialects are ethnolects formerly spoken by Jews throughout the Arab world. Under the ISO 639 international standard for language codes, Judeo-Arabic is classified as a macrolanguage under the code jrb, encompassing four languages: Judeo-Moroccan Arabic (aju), Judeo-Yemeni Arabic (jye), Judeo-Egyptian Arabic (yhd), and Judeo-Tripolitanian Arabic (yud).

Arabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The ISO assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā or simply al-fuṣḥā (اَلْفُصْحَىٰ).
