La Mont West, working under the guidance of
Alfred Kroeber and
Charles F. Voegelin, was an early pioneer in not only the
phonological analysis of Plains Sign Language but
sign language phonology in general. In his unpublished dissertation, he developed a notation system and analysed Plains Sign Language as having eighty-two
phonemes, which he called
kinemes, each being able to be broken down further in terms of
features. He analyzed signs as
morphologically complex that others such as
William Stokoe would analyze as
monomorphemic, and many of his findings were later rediscovered. His study of Plains Sign Language was taking place at the same time as Stokoe's seminal studies of
ASL phonology. • Direction – paralleling
vowels, there are eight distinctive directions, including the “directions” of either touching or being parallel to the referent. It can be combined with handshape to designate pointing or facing; with the referent, where it surfaces as placement; or with movement (i.e. motion dynamics), where it specifies the direction of movement. • Handshape – paralleling
consonants, nine basic handshapes can be rounded or unrounded to form a total of 18 distinct handshapes. •
Referent – numbering 40, these account for the greater phonemic inventory of Plains Sign Language compared to most
spoken languages. This can be a part of the hand, head, leg, body, or an external referent. • Motion-patterns – there are four motion-patterns consisting of the shape of any movement. Most signs are one-handed, including all
function signs, and these one-handed signs can be divided into static signs or those with movement. Two-handed signs are limited to signs where both hands are still, where one hand stays still and the other moves, or where both hands move. When both hands move, they move together in either parallel or intersecting motion. These constraints parallel the
Symmetry and Dominance Conditions later found in ASL. The Symmetry Condition requires that two-handed signs in which both hands move must be symmetrical in motion, while the Dominance Condition says that in two-handed signs involving two different handshapes, the passive hand is limited to certain movements and handshapes. Preliminary analysis has shown that Plains Sign Language seems to adhere to these conditions, and also favours
unmarked handshapes. West describes extensive
allophony, the
conditioning environments of which can be highly specific.
Prosody Users of Plains Sign Language show extensive
prosodic structure, which West divided into syllable-like packages and sub-packages,
word-like individual signs,
sentence-like phrases, and paragraph-like
utterances. Except for the
package and in stark contrast to most
deaf sign languages, where signs often flow freely into each other, the boundaries of each of these
prosodic units are consistently marked with one of three
junctures: The paragraph-final juncture exclusively marks the beginnings and ends of complete utterances, each having approximately the length and content of a paragraph. It may be
dropped at the beginning of an utterance. The paragraph- and phrase-final junctures can be used
interchangeably between signs. The paragraph-final juncture is more frequently used to separate list items and complete, sentence-like ideas, while the phrase-final juncture is preferred after incomplete ideas or
dangling clauses and is more likely to appear everywhere else. Any signs not separated by either the paragraph- or phrase-final juncture are
near-universally separated by the sign-final juncture, as well as packages within an open
compound, where multiple signs are used as a unit to refer to some idea or thing. Paragraph- and phrase-final junctures are extremely rare within open compounds. The largest units not separated by a juncture at all are unit signs, which can be a single package, a package and a handshape or terminal referent, a repeated package, or a closed compound, where multiple signs form a new sign. ==See also==
