Limbu Alphabet - Structure

Structure

As an abugida, a basic letter represents both a consonant and an inherent, or default, vowel. In Limbu, the inherent vowel is /ɔ/.

Letter IPA Notes
/kɔ/
/kʰɔ/
/ɡɔ/
/ɡʱɔ/
/ŋɔ/
/cɔ/
/cʰɔ/
/ɟɔ/
/ɟʱɔ/ Obsolete in modern Limbu.
/ɲɔ/ Obsolete in modern Limbu.
/tɔ/
/tʰɔ/
/dɔ/
/dʱɔ/
/nɔ/
/pɔ/
/pʰɔ/
/bɔ/
/bʱɔ/
/mɔ/
/jɔ/
/rɔ/
/lɔ/
/wɔ/
/ʃɔ/
/ʂɔ/ Obsolete in modern Limbu.
/sɔ/
/hɔ/

To change the inherent vowel, a diacritic is added. Shown here on /k/ (ᤁ):

Appearance IPA
ᤁᤡ /ki/
ᤁᤣ /ke/
ᤁᤧ /kɛ/
ᤁᤠ /ka/
ᤁᤨ /kɔ/
ᤁᤥ /ko/
ᤁᤢ /ku/
ᤁᤤ /kai/
ᤁᤦ /kau/

ᤁᤨ represents the same thing as ᤁ. Some writers avoid the diacritic, considering it redundant.

Initial consonant clusters are written with small marks following the main consonant:

Appearance IPA
ᤁᤩ /kjɔ/
ᤁᤪ /krɔ/
ᤁᤫ /kwɔ/

Final consonants after short vowels are written with another set of marks, except for some final consonants occurring only in loanwords. They follow the marks for consonant clusters, if any.

Appearance IPA
ᤁᤰ /kɔk/
ᤁᤱ /kɔŋ/
ᤁᤳ /kɔt/
ᤁᤴ /kɔn/
ᤁᤵ /kɔp/
ᤁᤶ /kɔm/
ᤁᤷ /kɔr/
ᤁᤸ /kɔl/

Long vowels without a following final consonant are written with a diacritic called kemphreng:

Appearance IPA
ᤁ᤺ /kɔː/
ᤁᤡ᤺ /kiː/
ᤁᤣ᤺ /keː/
ᤁᤧ᤺ /kɛː/
ᤁᤠ᤺ /kaː/
ᤁᤨ᤺ /kɔː/
ᤁᤥ᤺ /koː/
ᤁᤢ᤺ /kuː/

There are two systems for writing long vowels with syllable-final consonants. One system is simply a combination of the kemphreng and final consonant marks:

Appearance IPA
ᤁ᤺ᤰ /kɔːk/
ᤁ᤺ᤱ /kɔːŋ/
ᤁ᤺ᤳ /kɔːt/
ᤁ᤺ᤴ /kɔːn/
ᤁ᤺ᤵ /kɔːp/
ᤁ᤺ᤶ /kɔːm/
ᤁ᤺ᤷ /kɔːr/
ᤁ᤺ᤸ /kɔːl/

The other is to write the final consonant with the basic letter, and a diacritic that marks both that the consonant is final, and that the preceding vowel is lengthened:

Appearance IPA
ᤁᤁ᤻ /kɔːk/
ᤁᤅ᤻ /kɔːŋ/
ᤁᤋ᤻ /kɔːt/
ᤁᤏ᤻ /kɔːn/
ᤁᤐ᤻ /kɔːp/
ᤁᤔ᤻ /kɔːm/
ᤁᤖ᤻ /kɔːr/
ᤁᤗ᤻ /kɔːl/

This same diacritic may be used to mark final consonants in loanwords that do not have final forms in Limbu, regardless of the length of the vowel.

Glottalization is marked by a sign called mukphreng.

Appearance IPA
ᤁ᤹ /kɔʔ/

Famous quotes containing the word structure:

    A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.
    Guillaume Apollinaire (1880–1918)

    When a house is tottering to its fall,
    The strain lies heaviest on the weakest part,
    One tiny crack throughout the structure spreads,
    And its own weight soon brings it toppling down.
    Ovid (Publius Ovidius Naso)

    Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.
    Paul Tillich (1886–1965)
