Deaf-mute is a term which was used historically to identify a person who was either deaf using a sign language or both deaf and could not speak. The term continues to be used to refer to deaf people who cannot speak an oral language or have some degree of speaking ability, but choose not to speak because of the negative or unwanted attention atypical voices sometimes attract. Such people communicate using sign language. Some consider it to be a derogatory term if used outside its historical context; the preferred term today is simply "deaf".
Historical usage of the term "deaf-mute"
It is sometimes used to refer to other hearing people in jest, to chide, or to invoke an image of someone who refuses to employ common sense or who is unreliable. "Deaf and dumb"  is another historic reference to deaf people.
In the past deaf-mute was used to describe deaf people who used sign language, but in modern times, the term is frequently viewed as offensive and inaccurate. From antiquity (as noted in the Code of Hammurabi) until recent times, the terms "deaf-mute" and "deaf and dumb" were sometimes considered analogous to "stupid" by some hearing people.
The simple identity of "deaf" has been embraced by the community of signing deaf people since the foundations of public deaf education in the 18th century and remains the preferred term of reference or identity for many years. Within the deaf community there are some who prefer the term "Deaf" (upper-case D) to "deaf" (lower-case) as a description of their status and identity, in some cases also referring to those who come from families where deafness spans generations.
Classification as a deaf-mute has a particular importance in Jewish law. Because historically it was thought impossible to teach or communicate with them, deaf-mutes were not moral agents, and therefore were unable to own real estate, act as witnesses, or be punished for any crime. However, today when techniques for educating deaf people are known, they are no longer classed as such.
Deaf-mute people in history
The Ottoman Sultans used people referred to as "congenital deaf-mutes" (called in Turkish dilsiz or bizeban, i.e. "mute" or "without tongue") in their own personal service from the 15th century to the end of the Ottoman Empire. Due to their nature, they were often entrusted with confidential and delicate missions, including executions.
Deaf-muteness in art and literature
Stephen King's novel The Stand features a main character named Nick Andros who is referred to as "deaf-mute." Though deaf people almost always have a voice, King interpreted the term literally and made Nick unable to vocalize. However, he could read lips and make himself clearly understood by pantomiming and in writing.
The phrase is used in The Catcher in the Rye to indicate someone who does not speak his mind, and hears nothing, in effect becoming isolated from the world.
Chief Bromden, in One Flew Over the Cuckoo's Nest, is believed by all to be deaf and mute, but in fact he can hear and speak; he does not let anyone know this because, as he grew up, he was not spoken to (making him "deaf") and ignored (making him "mute").
The character Singer in the novel The Heart Is a Lonely Hunter, written in 1940, is referred to as "deaf-mute" throughout.
In the classic Zorro stories, television series, etc. Zorro's aid Bernardo, a mute, pretends that he can also not hear, in order to get information to aid his master in his fight for justice.
In the early 87th Precinct novels written by Ed McBain, Teddy Carella, the wife of Detective Steve Carella, was referred to as a "deaf-mute," but in later books, McBain stopped using the term. In the foreword to a reprinted edition of "The Con Man", originally published in 1957, McBain says, "A reader pointed out to me two or three years ago that this expression was now considered derogatory. Out the window it went, and Teddy is now speech-and-hearing impaired."
