Bamum script
Encyclopedia
The Bamum scripts are an evolutionary series of six scripts created for the Bamum language
Bamum language
Bamum , or in its French spelling Bamoun, is one of the Benue–Congo languages of Cameroon, with approximately a quarter million speakers. The language is well-known for its original script developed by King Njoya and his palace circle around 1895...

Mnemonic
A mnemonic , or mnemonic device, is any learning technique that aids memory. To improve long term memory, mnemonic systems are used to make memorization easier. Commonly encountered mnemonics are often verbal, such as a very short poem or a special word used to help a person remember something,...

Semi-syllabary
A semi-syllabary is a writing system that behaves partly as an alphabet and partly as a syllabary. The term has traditionally been extended to abugidas, but for the purposes of this article it will be restricted to scripts where some letters are alphabetic and others are syllabic.-Iberian...

In typesetting by hand compositing, a sort is a piece of type representing a particular letter or symbol, cast from a matrix mould and assembled with other sorts bearing additional letters into lines of type to make up a forme from which a page is printed.-See also:* History of western typography*...

Bamum Scripts and Archives Project
Bamum Scripts and Archives Project at the Bamum Palace is engaged in a variety of initiatives concerning the Bamum script, including collecting and photographing threatened documents, translating and in some cases hand-copying documents, creating a fully usable Bamum computer font for the inventory...

Function

The 80 glyphs of modern Bamum are not enough for all of the C
Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are , pronounced with the lips; , pronounced with the front of the tongue; , pronounced with the back of the tongue; , pronounced in the throat; and ,...

 V
Vowel
In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis. This contrasts with consonants, such as English sh! , where there is a constriction or closure at some...

 syllables of the language. The deficiency is made up for with diacritics and by combining glyphs with CV1 and V2 values, for CV2, making the script alphabetic for syllables not directly covered by the syllabary. Adding the inherent vowel of the syllable voices a consonant: tu + u = /du/, fu + u = /vu/, ju + u = /ʒu/, ja + a = /ʒa/, ʃi + i = /ʒi/, puə + u = /bu/.

The two diacritics are a circumflex (ko'ndon) that may be added to any of the 80 glyphs, and a macron
Macron
A macron, from the Greek , meaning "long", is a diacritic placed above a vowel . It was originally used to mark a long or heavy syllable in Greco-Roman metrics, but now marks a long vowel...

 (tukwentis) that is restricted to a dozen. The circumflex generally has the effect of adding a glottal stop to the syllable, for instance kâ is read /kaʔ/, though the vowel is shortened and any final consonant is dropped in the process, as in pûə /puʔ/ and kɛ̂t /kɛʔ/. Prenasalization is also lost: ɲʃâ /ʃaʔ/, ntê /teʔ/, ntûu /tuʔ/. Sometimes, however, the circumflex nasalizes the vowel: nî /nɛn/, pî /pin/, rê /rɛn/, jûʔ /jun/, mɔ̂ /mɔn/, ɲʒûə /jun/ (loss of NC as with glottal stop). Others are idiosyncratic: ɲʒə̂m /jəm/ (simple loss of NC), tə̂ /tɔʔ/ (vowel change), ɲî /ɲe/, riê /z/, m̂ /n/, ʃɯ̂x /jɯx/, nûə /ŋuə/, kɯ̂x /ɣɯ/, rə̂ /rɔ/, ŋkwə̂n /ŋuət/, fɔ̂m /mvɔp/, mbɛ̂n /pɛn/, tî /tɯ/, kpâ /ŋma/, vŷ /fy/, ɣɔ̂m /ŋɡɔm/.

The macron is a 'killer stroke' that deletes the vowel from a syllable and so forms consonants and NC clusters (/nd, ŋɡ/) that can be used for syllable coda
Syllable coda
In phonology, a syllable coda comprises the consonant sounds of a syllable that follow the nucleus, which is usually a vowel. The combination of a nucleus and a coda is called a rime. Some syllables consist only of a nucleus with no coda...

s. Consonantal /n/ is used both as a coda and to prenasalize an initial consonant. The two irregularities with the macron are ɲʒūə, read as /j/, and ɔ̄, read as /ə/.

The script has distinctive punctuation, including a 'capitalization' mark (nʒɛmli), similar to an inverted question mark, for proper names, and a decimal system of ten digits; the old glyph for ten has been refashioned as a zero.

Standard in October, 2010 with the release of version 6.0.
These are encoded in the Bamum Supplement block as U+16800-U+16A3F. The various stages of script development are dubbed "Phase-A" to "Phase-E" in the Standard. The character names note the last phase in which they appear. For example, U+168EE BAMUM LETTER PHASE-C PIN is attested through Phase C but not in Phase D.
