Colombian Sign Language (Spanish: Lengua de Señas Colombiana, LSC, Spanish pronunciation: [ˈleŋɡwa ðe ˈseɲas kolomˈbjana]) is the deaf sign language of Colombia.
Clark[2] notes that Peruvian, Bolivian, Ecuadorian and Colombian sign languages "have significant lexical similarities to each other" and "contain a certain degree of lexical influence from ASL" as well, at least going by the forms in national dictionaries.
The national Committee for the sign language promotes the research in the area, distributes the manual alphabet for spelling and the Grammar Dictionary and supports the organization for sign language teachers.
The now defunct national central of telecommunications TELECOM distributed a CD-ROM software for self-learning.
There is a growing interest for learning the sign language between the hearing people.
