Buci Sign Language (BSL), also referred to as Signed Buci or the Buci Manual System, is a constructed sign language and manual modality designed as the visual-gestural equivalent to the spoken constructed language Buci. While spoken Buci is characterized by an extensive inventory of diacritically modified consonants, lateral fricatives, uvular and pharyngeal consonants, and complex onset ligatures, the sign language counterpart translates both its lexical root structures and its orthographic inventory into a comprehensive system of fingerspelling (dactylology) and iconic, spatial grammar.[1]

Buci Sign Language serves both as a complete naturalistic sign language using spatial cherology and non-manual features, and as a manually coded language used for literal transcription and recitation of written Buci texts, such as the ns̒id lr̒t buc̒i ("Buci Alphabet Song").[2]

Spoken Buci phonology and orthography

[edit]

Buci Sign Language relies heavily on the structural and phonological inventory of spoken Buci. The spoken language utilizes a 32-letter modified Latin alphabet featuring turned comma and comma-below diacritics, as well as several specialized ligatures and borrowed glyphs, notably the Arabic letter ʿayn (ع) and modified numeral forms representing complex consonant-vowel clusters.[3]

Alphabet and phonological values

[edit]

The standard alphabet of Buci is organized into paired base and modified characters, alongside specialized phonotactic glyphs:

Manual system (cherology)

[edit]

In its fully gestural form, Buci Sign Language does not simply spell words letter by letter; rather, it uses a distinct phonological (cherological) system based on the four traditional sign language parameters: handshape, location, movement, and orientation, supplemented by non-manual features.[4]

Diacritic realization

[edit]

In the manual alphabet, diacritics are expressed systematically:

  • Turned comma above ( ̒ ): When modifying consonants (e.g., c̒ [ts], l̒ [ɬ], r̒ [ɣ]), the base handshape is articulated with an outward or lateral supination of the wrist, signaling a shift in manner from stop to fricative or central to lateral. For vowels (e.g., a̒ [ɑ], e̒ [ə]), the handshape is retracted toward the signer's torso, representing vowel backing or centralization.
  • Subscript comma ( ̦ ): Conveyed by a brief downward plunge of the hand, indicating lowered articulation or diphthongal glides.
  • Preposed apostrophe ( ̔ ): Expressed by an initial inward tap prior to releasing into the primary sign shape.

Non-manual markers

[edit]

Buci Sign Language incorporates non-manual markers (NMMs) such as eyebrow position, head tilts, and mouth shapes. In particular, words spelled or signed with the pharyngeal glyph ع are produced alongside a characteristic tightening of the throat and a slight head retraction, visually reflecting the oral articulation of [ʕ].[3]

Lexicon and syntax

[edit]

While fingerspelling is used for proper names and loanwords, standard Buci possesses independent lexical signs. Many lexical roots closely mirror the highly consonantal phonotactics of the spoken language.

Examples

[edit]
Written BuciSpoken IPAEnglish translationManual sign description
ns̒id lr̒t buc̒i/nʃid lɣt bu.tʃi/Buci Alphabet SongCompound sign: fingerspelled N-S̒-I-D followed by rhythmic two-handed wave (song) and the emblem for the Buci language.
mzq̒/mzɡ/MusicTwo hands shaped in the m configuration tracing melodic waves outward from the ears.
xs̒c̒dع/χʃts.dʕ/The End / ConclusionBoth open hands held horizontally, crossed outward across the chest, ending with a claw retraction to indicate the terminal ع.

Syntax

[edit]

Buci Sign Language typically follows a Topic-Comment structure, differing from the more rigid SVO tendencies of the spoken register. Spatial loci are established in front of the signer to indicate pronominal reference and verbal agreement, allowing for efficient communication that bypasses the complex consonant clusters found in speech.[2]
