Spanish as spoken by the
Jewish community of Tetuan went through a process of re-Hispanisation starting in the 19th century, whereby various linguistic aspects of Haketia were influenced by
Castilian Spanish. According to Isaac Guershon, this process was sustained by Jewish merchants' commerce between western Mediterranean cities, especially between Tetuan and
Gibraltar. Tetuani Jews came to pronounces 's' and 'j' according to the new Castilian pronunciation, for example. This process was greatly accelerated by the
Hispano-Moroccan War (1859–1860) and the Spanish occupation of Tetuan (February 6, 1860 – May 1862). According to Moisés Orfali, the establishment of the
Spanish protectorate in northern Morocco was the "mortal blow" to Haketia, and by the 1920s, texts published about Haketia could be considered documentation of a dying language. The Asociación Hispanojudía de Tetuan sought to teach 'pure Castilian'. == In Oran ==
