The Plains Indian sign languages (PISL), also known as Plains Sign Talk,[3] are various manually coded languages used, or formerly used, by various Plains Nations of the United States and Canada. The best known is Plains Standard Sign Language, a contact language (international auxiliary language) used between these peoples.


PISL's antecedents, if any, are unknown, due to lack of written records, but the earliest records of contact between Europeans and Native Americans of the Gulf Coast region in what is now Texas and northern Mexico note a fully formed sign language already in use by the time of the Europeans' arrival there.[4] These records include the accounts of Cabeza de Vaca in 1527 and Coronado in 1541.

As a result of several factors, including the massive depopulation and the Americanization of Native North Americans, the number of PISL signers declined from European arrival onward. In 1885, it was estimated that there were over 110,000 "sign-talking Indians", including Blackfoot, Cheyenne, Sioux, Kiowa and Arapaho.[5] By the 1960s, there remained a "very small percentage of this number".[5] There are few PISL signers today.[6]

William Philo Clark, who served in the United States Army on the northern plains during the Indian Wars, was the author of The Indian Sign Language, first published in 1885, The Indian Sign Language with Brief Explanatory Notes of the Gestures Taught Deaf-Mutes in Our Institutions and a Description of Some of the Peculiar Laws, Customs, Myths, Superstitions, Ways of Living, Codes of Peace and War Signs, is a comprehensive lexicon of signs, with accompanying insights into Indigenous cultures and histories. It remains in print.


Sign language use has been documented across speakers of at least 37 oral languages in twelve families,[7] spread across an area of over 2.6 million square kilometres (1 million square miles).[8] In recent history, it was highly developed among the Crow, Cheyenne, Arapaho and Kiowa, among others, and remains strong among the Crow, Cheyenne and Arapaho.

Each nation used a distinct manually coded language,[citation needed] as was the case in aboriginal Australia. In addition, there was a trade pidgin that may have never been extensively used, or was only used by a well-traveled elite. This contact language may be distinguished as Plains Standard SL, as opposed to the generic term Plains Indian SL for the various ethnic forms. These were reportedly not used by the deaf, who used home sign instead.[citation needed]

Signing may have started in the south, perhaps in northern Mexico or Texas, and only spread into the plains in recent times, though this suspicion may be an artifact of European observation.[citation needed] Sign, or at least contact sign, spread to the Sauk, Fox, Potawatomi, Cherokee, Chickasaw, Choctaw, and Caddo after their removal to Oklahoma. Via the Crow, it replaced the divergent Plateau Sign Language among the eastern nations that used it, the Coeur d'Alene, Sanpoil, Okanagan, Thompson, Lakes, Shuswap, and Coleville in British Columbia, with western nations shifting instead to Chinook Jargon.

The various nations with attested use, divided by language family, are:

A distinct form is also reported from the Wyandot of Ohio.

Supalla reports a clan of Navajos that has several non-ASL-speaking deaf members; both deaf and hearing use a sign language that Supalla says is related to "Old Indian Sign Language".[9]

Additionally, it is known that there exists a Plains Sign Talk language within the Blackfoot Confederacy. Little is known about the language aside that it is used by Deaf community members as well as by the community at large to pass on "oral" traditions and stories.[10]


There are four basic parameters of PISL sign: the location of the hand, its movement, shape, and orientation:[11]

  • Location—this involves the spacial placement of a sign.[12] Signs may change meaning when placed in a different location, for example, in front of the face as opposed to in front of the torso.[13]
  • Movement—this involves, as implied, the way the hands move when forming the sign.[12] For example, in PISL, the signs AFTERNOON and MID-DAY form minimal pairs as they are both formed exactly the same, the only difference being that MID-DAY is stationary and AFTERNOON moves from above the head to the side in an arching motion.[14][15]
  • Handshape—as implied, each sign takes on a certain shape in the hand, called a handshape. The handshapes of signs are a very key parameter. For example, the signs YES and I-KNOW are the same in all parameters except for the handshape; in YES the hand makes the PISL J shape, and in I-KNOW the hand takes the L shape.[14]
  • Orientation—this refers to the orientation of the palm.[12] This is clearly seen in the PISL signs ABOVE and ADD. Both involve having the left hand act as a base from which the right hand rises, and both have the same location, movement, and handshapes; however, in ABOVE, the non-dominant hand is palm down, and in ADD the non-dominant hand is palm up.[15]

There may be other parameters, such as facial features. However, these function like suprasegmentals, and the four parameters listed above are the crucial ones.[12]

Although the parameters of sign are listed separately below, in actuality they co-occur with the other parameters to make a single sign.[12] It is not clear how many of the differences were distinctive (phonemic).


The Bureau of American Ethnology published a glossary of PISL signs that illustrate the handshapes involved.[16] They assigned them alphabetic letters.[why?]

  • Fist, thumb in front of fingers (A or B)
  • Fist, thumb at side of fingers (C)
  • Fingers clenched, thumb touching middle of index finger (D)
  • Fingers hooked, thumb touching back tip of index finger (E)
  • Fingers hooked, thumb at side of fingers (F)
  • Fingers hooked, thumb touching tips of fingers (G)
  • Fingers slightly bent, thumb at side tip of index finger (H)
  • Fist, except index finger forming hook with thumb holding tip of index finger (I)
  • Fist, except index finger fully extended (J, K, or M)
  • Fist, except index finger and thumb extended, thumb bends at last joint to form 90 degree angle with index finger (L)
  • Fist except index and middle fingers fully extended (N)
  • Thumb, index, and middle finger pointing upward and separated, ring finger and pinky curved horizontally (O)
  • All fingers and thumb pointing upward and separated, palm cupped (P and Q)
  • All fingers and thumb fully extended and separated (R)
  • All fingers and thumb fully extended and held together (S and T)
  • Fingers gathered to a point, palm cupped, with thumb in the middle (U)
  • Fingers slightly bent, thumb at side of index finger (V)
  • All fingers and thumb extended, relaxed (Y)
