Signed languages of Mexico
Mexican Sign Language and others
Signed languages are used by Deaf people in many parts of the world. In Mexico, one signed language is used throughout most of the country. It is known in English as Mexican Sign Language and in Spanish by various names including Lenguaje de Signos Mexicano and Lengua de Señas Mexicana. In both English and Spanish, it may be referred to by the initials LSM. The number of people who depend on it as a primary means of communication is unknown, but the Deaf community in Mexico seems to be larger than many whole families of indigenous languages in the country.
LSM is distinct from other signed languages, such as American Sign Language (ASL, used in the United States, Canada, and many other countries), the signed languages of Spain, and those of other countries in Latin America. It has its own vocabulary and grammar; the latter is different from the grammar of Spanish, although there is also a style of signing in Mexico that arranges LSM signs according to Spanish grammatical patterns. LSM is truly a language in its own right, fully capable of expressing as wide a range of thoughts and emotions as any other language.
LSM is not related to any other language in Mexico, but has some similarities to American Sign Language and other signed languages influenced by or derived from Old French Sign Language.
Although LSM is the largest and most widespread signed language used in Mexico, it is not the only one; there is another one used in some Mayan communities in the Yucatan.
