Black American Sign Language, Tactile ASL (TASL). Some lexical variation across the United States and much of Canada, but intelligibility is high among all dialects called ASL. Black American Sign Language developed in schools for African-American deaf people due to segregation in the southern United States. It contains some distinctive vocabulary and grammatical structure. Tactile ASL (TASL) is used throughout the United States by and with deaf-blind people, especially those with Usher’s Syndrome, concentrations of which are found in Louisiana and Seattle. TASL uses ASL vocabulary and grammar, except (1) the deaf-blind person receives signs through touch by feeling signs in the palms, and (2) minor syntactic modifications to compensate for the deaf-blind person’s lack of access to the signer’s facial expressions. Some deaf-blind people learn Braille for reading English. Dialects or closely-related languages derived from ASL, are used in many other countries. Lexical similarity: 57% between modern ASL and French Sign Language (LSF) [fsl] on a comparison of 872 signs. Although the 2 are related, ASL has undergone substantial creolization (Woodward 1975, 1976).

American Sign Language is different from Signed English, which refers to a range of signing registers that reflect some influence from English. At the extreme end are Signing Exact English (SEE) and Seeing Essential English (SEE2), artificially-constructed systems that attempt to match English word and morpheme order exactly. English-influenced signing that does not follow English grammar exactly is generally called contact signing or Pidgin Signed English. Deaf schools and interpreters in mainstream settings may use any one of these registers.
