Jōnagan. — Jōnagan is given, in the Madras Census Report, 1901, as the name applied to "Musalman traders of partly Hindu parentage. The word is from the Tamil Sōnagan, which means Arabia, and is not strictly the name of any Musalman tribe, but is a loose term applied by the Tamils to Musalmans of mixed descent." In the Gazetteer of South Arcot, Mr. Francis says that "the term Jōnagan or Sōnagan, meaning a native of Sōnagan or Arabia, is applied by Hindus to both Labbais and Marakkāyars, but it is usually held to have a contemptuous flavour." According to another version, Jōnagan is applied to sea-fishermen and boatmen, and the more prosperous traders are called Marakkāyars. In a note on the Māppillas of Malabar, Mr. Padmanabha Menon writes that "the Muhammadans generally go by the name of Jōnaga Māppillas. Jōnaka is believed to stand for Yavanaka, i.e., Greek."
