Mandombe script

Mandombe has consonant letters and vowel letters which are combined into syllabic blocks, rather like hangul. All letters are based on a square S or 5 shape. The six vowels are distinguished by numerals added to the right of the 5-shape. The consonants fall into four 'groups', or shapes, which are distinguished by adding a short stroke to the 5-shape for three of the groups; and into four 'families', or orientations, which are distinguished by reflecting and rotating the letter shapes. The four families of consonants are attached to the same corner of the vowel, which is reflected or rotated to match the consonant, so that the consonant resides in a different corner of the syllabic block depending on its orientation. Unlike Pitman shorthand, which also distinguishes consonants by rotation, in Mandombe the groups and families do not form natural classes, apart from a fifth group of fricatives and affricates made by inverting one of the four basic groups. Vowel sequences and nasal vowels are created with diacritics, prenasalized consonants by prefixing n (the basic 5-shape), and consonant clusters by inserting a consonant between the two parts of the vowel (between the 5-shape and the additional strokes).

Vowel letters are composed of two parts: the basic 5-shape of the Mandombe script plus a numeral, or—in the case of ü (/y/)—by modifying the basic u vowel letter. Vowel 1 is i, vowel 2 u, vowel 3 e, vowel 4 o, and vowel 5 a.

A vowel can be written individually and form a syllable on its own. In a vowel sequence or diphthong, however, a diacritic is used for the second vowel or part of the vowel. That is, lio (two syllables) is written li plus the diacritic for o, while mwa (one syllable) is written mu plus the diacritic for a. Diacritics come at the end of the last stroke of the vowel. While there is a diacritic for u, sequences ending in u are instead generally written as two full syllables, the second being wu. This strategy is apparently also employed in some other cases rather than using diacritics.^{[citation needed]}

Ü is  . It has no diacritic.

There are four basic consonant shapes. Each shape (base character) can be reflected horizontally, vertically, or both to represent a different consonant; the four consonants thus formed are considered to be a group, and consonants reflected in the same way are considered to be a family. These consonants are combined with vowels, which are similarly reflected, to create syllables.

Family 1

The consonant with the basic orientation is attached to the lower left of the vowel

Family 2

The consonant-plus-vowel is reflected both horizontally and vertically (rotated 180°)

Family 3

The consonant-plus-vowel is reflected horizontally

Family 4

The consonant-plus-vowel is reflected vertically

Vowel diacritics are reflected along with the main vowel.

The use of geometric transformation is also present in Pitman shorthand and Canadian Aboriginal Syllabics, though Mandombe consonants in the same group do not seem to have any phonological relationship (except the fifth group named mazita ma zindinga, in which all consonants are affricates and fricatives).

• Prenasalisation of consonants is indicated with a variation on   (n) disconnected from the vowel. This always joins the consonant body, else certain signs could be read in more than one way.
• Nasalisation of the vowel is marked by an attached diacritic:  .
• If   is placed between the two separable parts of the vowel glyph, it represents an intervening /r/.

The digit for 1 resembles the Arabic numeral 1, and 2–5 are based on this shape. 6 and 9 are square versions of Arabic 6 and 9, and 7–8 are formed by reflecting them.

1–5 are also the shapes used for the vowels i u e o a.

A period is used as a word divider to separate words.

The punctuation corresponds to that of the Roman alphabet. A comma has the form of a short line,  , a period a turned vee,  , like the diacritic for o, and a colon and semicolon combinations of these (semicolon î, colon double  ). The exclamation mark is like a lambda, λ, and the question mark is like a turned Y, ⅄.
