Many/most endangered languages are unwritten
Literacy is one factor that may help in preserving them
SIL has done a lot in this area
![Page 3: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/3.jpg)
Aren’t all languages written?
Nope 6909 languages are estimated
(see ethnologue.com) 1500-2000 of these are unwritten
![Page 4: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/4.jpg)
Why bother? Can’t they all learn English?
Literacy is one of the factors that helps preserve an endangered language
Identity – your language is you! Scientific knowledge
![Page 5: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/5.jpg)
What’s an “orthography”?
Alphabet or other symbols Spelling rules Word divisions Punctuation
![Page 6: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/6.jpg)
Alphabet or…?
Most languages use an alphabetic system, with consonants and vowels
Some use syllabaries - a symbol is a syllable. Cherokee:
sa Ꮜ se Ꮞ si Ꮟ so Ꮠ
suᏑ
![Page 7: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/7.jpg)
![Page 8: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/8.jpg)
Alphabet – or…?
A few languages use a logographic system, where a symbol is a whole word. Chinese:
河 hé “river“ 貓 māo "cat”
We’ll be focusing on alphabetic systems today
![Page 9: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/9.jpg)
Which letters to use?Basic concept – one letter per “sound”
Not just a phonetic sound:“pool” vs. “spool” [phul] [spul]
Two “p” sounds phonetically, but we think of them as one. No difference in meaning.
![Page 10: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/10.jpg)
[phul] [spul]
Two “p” sounds phonetically, but psychologically, ONE sound. No difference in meaning.
This psychologically real sound is called a phoneme.
![Page 11: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/11.jpg)
Hindi [pəm, phəm] are two different words! [p, ph] makes a difference in meaning.
Both English and Hindi have phonetic [p, ph ]
Psychologically, ONE sound in English, TWO sounds in Hindi
One phoneme for English, two for Hindi
![Page 12: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/12.jpg)
Back to the alphabet… For English, one “p” phoneme,
and so all we need is one “p” letter.
For Hindi, two “p” phonemes, so we need two “p” letters
But there’s more besides linguistics!
![Page 13: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/13.jpg)
Practicalities… Develop materials for reading:
– Primers– Variety of materials (500 pages?)
Devise teaching strategies Train trainers = teachers All this assumes the local people are in
favor of literacy…

Why do Komas read?
Bible reading
Privacy of letters
Town signs
![Page 24: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/24.jpg)
NON-linguistic factors Government policies
The Bureau of Ghana Languages used to disallow all tone marks in orthographies.
In 1979, Cameroon established a unified alphabet. New orthographies must conform.
An orthography should be acceptable to governing authorities
![Page 25: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/25.jpg)
Sociolinguistic Factors
“All orthographies are political”
![Page 26: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/26.jpg)
Dialects Konni (Ghana): Main dialect has /h/
Nangurima has /ŋ/: hɔgʊ� vs. ŋɔgʊ� ‘woman’
Can one orthography serve all dialects?
Uni-lectal – choose the prestigious dialect Konni orthography uses <h>,
Nangurima pronounces it as [ŋ].
![Page 27: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/27.jpg)
More on Dialects Multi-lectal –orthography has
elements of several dialects; one group is not favored
But it doesn’t represent the actual speech of anyone.
European languages, Nynorsk, Dagaare
![Page 28: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/28.jpg)
Attitudes toward other languages
Local people may want the orthography to “look like” a major language
In Ghana,<r> is in most orthographies,
(whether a phoneme or not!) under the influence of English.
![Page 29: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/29.jpg)
More attitudes People may want the orthography not
to look like another language.
Ghana: Konkombas use <ln> word-finally. The related Kombas spell it <nl>.
Guatemala: Existing orthographies used <qu, c>, but a Mayan resurgence wanted <k>, to distinguish it from Spanish.
![Page 30: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/30.jpg)
Groups and orthographies
Sometimes orthographies become attached to a certain group: “You’re an evangelico, I’m a Catholic, so I support this one.” Religious groups, political groups, clans, etc.
Include all stakeholders in orthography planning and decisions
Examine previous orthographies, and who designed, supports, and uses them
![Page 31: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/31.jpg)
Choice of entire scripts More than just individual symbols Cyrillic vs. Arabic vs. Roman-based
Давлки -- ألفبائي --- dabigu
Line drawings vs. photographs vs. SignWriting for signed languages
Sometimes good to publish with 2 or even 3 scripts in the same book!
![Page 32: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/32.jpg)
An orthography is an expression of a people’s identity. People accept or reject an orthography based on sociolinguistic factors. If a group doesn’t want to use an orthography, it doesn’t matter how linguistically sound it is. “What the people want” is not just one more factor; it is the most critical factor in acceptance of an orthography.
![Page 33: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/33.jpg)
Educational factorsTransferability to other languages Latin America: <qu> and <c> used for /k/,
and punctuation <¿ ... ?> as in Spanish.
Ghana: How to consistently represent /tʃ/ in Ghanaian languages? Obvious to some that it should be <ch>, obvious to others that it should be <ky>. It depended on the language of transfer (and identity): English or Akan?
![Page 34: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/34.jpg)
Readability
Want good visual discrimination, little “cluttering”
Extreme examples:
n ņ ɲ ɳ ŋ too many symbols resemble each other
![Page 35: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/35.jpg)
Readability
a a� a� a�� too many stacking diacritics
Font selection: Sans-serif is better for beginners
![Page 36: Extreme Literacy Developing an orthography for an unwritten language Dr. Michael Cahill SIL International Endangered Languages Week 2011, UTA](https://reader036.vdocument.in/reader036/viewer/2022062421/56649e035503460f94aedd7a/html5/thumbnails/36.jpg)
Practical Production Factors
Fonts!– A past problem: what can a typewriter or
local printer do?
28 years ago, I ordered “custom keys” on a new manual typewriter (ŋ, ɔ, ɛ)

Unicode fonts are ‘best practice.’

“ Without literacy, our language was in the process of being exterminated...He who loses his mother tongue is just a slave to him who is of the lowest class...But now, even if I die today, I will die happy, because my children have a language which will endure and that they can call their own.” Josué Koné, Miniyanka speaker, Mali
