persons.

Economy The Paisa Region coincided with the important economic centers of Colombia like the Metropolitan Area of Medellín (textile, industries like appliances, automobiles and chemicals, services like health care and fashion); the Colombian Coffee-Growers Axis in agriculture and other economic activities like flower growing, cattle, gold and coal mines, tourism and others. Culture Language The way Paisas speak Spanish, also known as Antioquean Spanish, is distinctive within Colombia. Paisas are said to speak Spanish fast and soft. They have many local and regional expressions that are opaque even for other Colombians. From the rural Paisa dialect, a popular urban version called Parlache developed. Voseo (using vos instead of tú): In colloquial speech, Paisas use vos as the second person singular informal pronoun (instead of tú) and usted for formal address, although it is common to use usted even with relatives and friends. However, vos is restricted to colloquial use and, unlike exclusively voseo regions that use it for official purposes like the press and government, vos in the Paisa Region is rarely used in official documents. Several Paisa writers (such as Tomás Carrasquilla, Fernando González Ochoa, Manuel Mejía Vallejo, Fernando Vallejo, and Gonzalo Arango) use vos in their works as a distinct marker of the Paisa identity. However, the use of tú is well known due to the immigration of Colombian groups like the Costeños. Seseo (lack of distinction between and ): As with most American dialects of Spanish, Paisas do not distinguish ‹s› from ‹z› or soft ‹c›. While seseo is dominant, the Paisa /s/ is articulated as an apicoalveolar , a sound transitional between and , as in central and northern Spain and southern Central America. The apicoalveolar 's' was influenced by Basques, Catalans, and Extremadurans, and seseo was influenced by Andalusians and Canarians. Yeísmo (merger of into
