Stokoe notation () is the first phonemic script used for sign languages. It was created by William Stokoe for American Sign Language (ASL), with Latin letters and numerals used for the shapes they have in fingerspelling, and iconic glyphs to transcribe the position, movement, and orientation of the hands. It was first published as the organizing principle of Sign Language Structure: An Outline of the Visual Communication Systems of the American Deaf (1960), and later also used in A Dictionary of American Sign Language on Linguistic Principles, by Stokoe, Casterline, and Croneberg (1965). In the 1965 dictionary, signs are themselves arranged alphabetically, according to their Stokoe transcription, rather than being ordered by their English glosses as in other sign-language dictionaries. This made it the only ASL dictionary where the reader could look up a sign without first knowing how to translate it into English. The Stokoe notation was later adapted to British Sign Language (BSL) in Kyle et al. (1985) and to Australian Aboriginal sign languages in Kendon (1988). In each case the researchers modified the alphabet to accommodate phonemes not found in ASL. The Stokoe notation is mostly restricted to linguists and academics. The notation is arranged linearly on the page and can be written with a typewriter that has the proper font installed. Unlike SignWriting or the Hamburg Notation System, it is based on the Latin alphabet and is phonemic, being restricted to the symbols needed to meet the requirements of ASL (or extended to BSL, etc.) rather than accommodating all possible signs. For example, there is a single symbol for circling movement, regardless of whether the plane of the movement is horizontal or vertical. Writing direction Stokoe notation is written horizontally left to right like the Latin alphabet (plus limited vertical stacking of movement symbols, and some diacritical marks written above or below other symbols). This contrasts with SignWriting, which is written vertically from top to bottom (plus partially free two-dimensional placement of components within the writing of a single sign). Symbol usage Stokoe coined the terms tab ("tabula" or sign location), dez ("designator" or handshape & orientation), and sig ("signation" or motion & action). These are used to categorize features of sign-language phonemes, somewhat like the distinction between consonant, vowel, and tone is used in the description of oral languages. A sign is written in the order tab-dez-sig: TDs. Compound signs are separated with a double
