Abjad

System ysgrifennu yw abjad lle ysgrifennir cytsain yn unig neu'n bennaf. Yn yr iaith dechnegol, wyddor gystain. Mewn effaith rhaid i'r ddarllenwyr gasglu neu gyflenwi llafariad priodol fel arall. Y term yw fathiad a gyflwynwyd yn 1990 gan Peter T. Daniels ar awgrymiad gan Wolf Leslau, ieithydd oedd yn arbenigo ar ieithoedd Semitig; mae'r term yn seiliedig ar derm o iaith Ethioptig.^[1] Mae termau eraill ar gyfer yr un cysyniad yn cynnwys: sgript ffonemig rannol, sgript ffonograffig ddiffygiol llinellol segmentol, ysgrifennu cytseiniol a'r 'wyddor gytsain.^[2]

Daw'r llais "abĝad" o lythrennau cyntaf yr wyddor Arabeg hanesyddol (ac nid, felly, allan o'r fersiwn gyfredol sy'n cael ei dosbarthu fel llythrennau atynt sy'n cynnwys ar sail eu ffurf graffig): 'alif, bā', ǧīm a dal, y mae ei hawl acrostig wedi'i ffurfio o'i abjad (Arabeg: أﺑﺠﺪ).

It cannot be subsumed under either of the other terms. A suitable name for this type would be alephbeth, in honor of its Levantine origin, but this term seems too similar to alphabet to be practical; so I propose to call this type an "abjad," [Footnote: I.e., the alif-ba-jim order familiar from earlier Semitic alphabets, from which the modern order alif-ba-ta-tha is derived by placing together the letters with similar shapes and differing numbers of dots. The abjad is the order in which numerical values are assigned to the letters (as in Hebrew).] from the Arabic word for the traditional order6 of its script, which (unvocalized) of course falls in this category... There is yet a fourth fundamental type of script, a type recognized over forty years ago by James- Germain Fevrier, called by him the "neosyllabary" (1948, 330), and again by Fred Householder thirty years ago, who called it "pseudo-alphabet" (1959, 382). These are the scripts of Ethiopia and "greater India" that use a basic form for the specific syllable consonant + a particular vowel (in practice always the unmarked a) and modify it to denote the syllables with other vowels or with no vowel. Were it not for this existing term, I would propose maintaining the pattern by calling this type an "abugida," from the Ethiopian word for the auxiliary order of consonants in the signary."
