Topological approach to selecting a shape from the set of morphs of a Uyghur letter
There are 32 letters in Uyghur Arabic Alphabet that is used as the official written system. Among these 32 letters, there are 26 consonants and 8 vowels.
32 Letters = 26 Consonants + 8 Vowels
Not sure what consonants and vowels are? Don't bother the definition for now. Here are some examples in English:
Consonants: , b, c, d, , f, g, ...
Vowels : a, , , ,e, , , ..., i, ..., o, ..., u, ...
In Uyghur language, however, here are the alphabet:
Consonants: ب، پ، ت، ج، چ، خ، د، ر، ز، ژ، س، ش، غ، ف، ق، ك، گ، ڭ، ل، م، ن، ھ، ۋ، ي
Vowels : ئا، ئە، ئې، ئى، ئو، ئۇ، ئۆ، ئۈ
Each letter has several shapes, namely, 2, 4 or 8 shapes for each letter. For example: ئا (A) has 4 shapes, ئې (É) has 8 shapes; د (D) has 2 shapes and ب has 4 shapes.
So how do you know decide which shape to use for a particular letter in a particular word? It is easy. Use the one that makes sense! Here is what I mean by that.
Let's first consider the four shapes below.
│, ┴, └, ┘
If you are given a set of four shapes as below, and the only rule is *always do not have open ends horizontally (well, that is how we write letter, right? Not vertical.) Then we could assemble them into something like this below:
Right: (notice that no open ends on left, right or middle)
└┘
└┴┘
└┘└┴┘
└┘│└┴┘
└┴┘││
Wrong: (notice the open ends on left, right or middle)
┘└
┴┴┘
└│┘
When teaching these, I would stand in front of the class, and use my arms to get the shapes above: extend my arms to be ┴, only extend right arm to be └, and stand still with arms on both sides (as soldiers) to be │. Well, you get the point, and amused.
We have base shapes {│, ┴, └, ┘}. Now let's do the classification. Here are the rules:
All consonants have either 2:{│, ┘} or 4:{│, ┴, └, ┘} shapes;
All vowels have either 4:{│, ┘} or 8:{│, ┴, └, ┘} shapes; (you are right, there are only 2 and 4 stuff in the set; look below);
Each shape of vowels (not consonants) have two forms: with ء (e.g. ┘ء ) or without ء (e.g. ┘)
We will come to ء later. Let's first contentrate of the first two rules above.
All consonants of shape class 2:{│, └} are: د، ر، ز، ژ، ۋ، ھ.
All other consonants are of shape class 4:{│, ┴, └, ┘}.

All vowels of shape class 4:{│, ┴, └, ┘} are: ئې، ئى. (é, i)
All other vowels are of shape class 2:{│, └}.
Letter are connected in a way that reduces open ends. An easier way of saying this is:
Always hold hands whenever possible. (Be friendly!)
Most words native to Uyghur language keeps the consonants and vowels in it balanced. A counter example would be a word like strict where we only have one vowel i in the word, while 5 consonants strct are in the word. In Uyghur language, we mostly have words such as dada (father), ana (mom), bala (child) etc.
Here is also a simple rule for the structure of the words. But first, we need to talk about Syllable.
I will keep it simple and this is not a formal definition.
A syllable is a smallest possible meaningful phonetic component of a word. For example, mo·ther has two syllables: mo and ther. More examples are: hap·py, fa·ther. In Uyghur language, it is the same. Using the words we used above: da·da, a·na, ba·la.
Now the rules. We use A for represent vowels, and B to represent consonants.
The syllables in most words native to Uyghur language are: syllables={
A,AB,BA,BAB} (notice the absence of structures such asBB,BBA,ABBetc.)
When a syllable begins with a vowel, then the vowel adds a ء to its shape.
In short, if a syllable is of form A or AB, then the A has ء.
Let's first give examples to the first rule above. Consider the words da·da. We can see that this word has two syllabes: da and da. d is a consonant, therefore B, and a is a vowel, therefore A. Thus this word has two syllables of shape BA among the four shapes above. Since both BA does NOT begin with a vowel (it begins with d), therefore we can forget about ء. We can write the word even without knowing the letters themselves! Let's try. d is a consonant shape set in 2:{│, └}, a is not in the vowels shape set 4:{│, ┴, └, ┘} (we only have two for these but a is not any of the two!). Note that, Uyghur Arabic script is written from right to left. Lets' write it:
- Choose a shape from
2:{│, └}for the first letterd. Since we are writing from right to left, and cannot have open ends horizontally, we cannot choose└from the two2:{│, └}. Let's choose│. - Choose a shape from
2:{│, └}for the first lettera. The first letter on its right does not offer a hand to it, so it cannot hold hands using shape└. Choose│again. - Consider the next
d. Same logic, and we choose│for the previous (second) letteradoes not offer a hand. - Consider the last letter
a. Follow the same logic. And we choose│for the previous (third) letterdalso does not offer a hand. - It seems they are not so friendly!
- We have our word
dadaat last:││││. (four standing side by side, without holding hands).
Now consider ba·la. ba is of syllables structure BA, la is of syllables structure BA as well. So no ء. b is from 4:{│, ┴, └, ┘}, and a is form 2:{│, └}.
bis the first letter of shape4:{│, ┴, └, ┘}. Sincebis the first letter on the right, we can choose either from│, ┘. Let's move on.ais the letter next tobof shape2:{│, └}. Let's be friendly! We choose└foraso that it offers a hand to the previousb.bcan now hold hands withausing shape┘.- This leaves us with shape
└┘for the first two letterba. - We can find that
laare also in the same situnation:lis also of the shape4:{│, ┴, └, ┘}asbwas! Solacan also be friends:la=>└┘ - In the end, we have
bala=>└┘└┘.
Let's consider some more words. bulut (cloud), su (water), kala (cow), siz (you), asman (sky).
bulut (cloud): (work this out yourself before looking at the answer below!)
The letter and their shape classes are:
b<-4:{│, ┴, └, ┘}u<-2:{│, └}l<-4:{│, ┴, └, ┘}u<-2:{│, └}t<-4:{│, ┴, └, ┘}
Let's put them together and make sure they get along well (become friends). Here is the selection. Note that the syllables are of form BA·BAB, so no syllable that begins with a vowel. We can forget about ء.
b<-┘u<-└l<-┘u<-└t<-└
We get: │└┘└┘
su (water): (work this out yourself before looking at the answer below!)
The letter and their shape classes are:
s<-4:{│, ┴, └, ┘}s<-2:{│, └}
This is simple. It is one syllable and of form BA. Does not begin with a vowel. So we get └┘.
kala (cow): (work this out yourself before looking at the answer below!)
Look up the rule table for the letter and their shape classes. Which class does k, a, l belong? (We can choose from classes 4:{│, ┴, └, ┘}, 2:{│, └}).
kala has a syllabus form of BA·BA. We can safely forget ء. We get: └┘└┘.
siz (you): (work this out yourself before looking at the answer below!)
Look up the rule table for the letter and their shape classes. Which class does s, i, z belong? (We can choose from classes 4:{│, ┴, └, ┘}, 2:{│, └}).
We find that they all belong to 4:{│, ┴, └, ┘}. Imagine three friends who are willing to do anyting for each other. You are going to take a picture of them, so they stand in a line, holding hands. So the most happy case for them is: └┴┘.
And syllabus form is BAB threfore no ء.
asman (sky): (work this out yourself before looking at the answer below!)
The letter and their shape classes are:
a<-2:{│, └}s<-4:{│, ┴, └, ┘}m<-4:{│, ┴, └, ┘}a<-2:{│, └}n<-4:{│, ┴, └, ┘}
In order to a) connect those letters and b) be friendly, we have to choose the following set:
a<-│s<-┘m<-┴a<-└n<-│
We get: │└┴┘│.
Notice that the syllables of as·man as has a form of AB·BAB. The first syllable AB begins with a vowel a (as A in our representation). Therefore we add ء. In the end, we get:
We get: │└┴┘│ء.
Isn't it amazing that there is only one possible way to connect them!? Well, that is the by the laws of topology. But we can forget about them. A simple rules is: if people choose how friendly they are going to be to their neighbors (friendly to the left ┘, to the right └, or better, to both neighbors ┴, or worse, to none of the neibours │, then you can always satisfy them in a neighborhood (not in a building, but a contryside where you have houses side by side!)
This set of rules are a result of my continuing effort in trying to teach our language and its script to students, freinds who speak Uyghur but trying to learn how to write, and also to friends who do not speak the language itself, but tryint to learn. This topology based approach is very universal so that students can learn how to write before they are familiar with the full alphabet and all the different shapes of each and every letters. You can even play with this set of rules in your own language!
I hope this routine could be taught in schools where kids can play in their classes taking roles as the four base shapes. This way of learning is much fun, and can give very clear idea fo the script for the students from the beginnin.
