|ISO 15924||Mand, 140 , Mandaic, Mandaean|
The Mandaic alphabet is thought to have evolved between the 2nd and 7th century CE from either a cursive form of Aramaic (as did Syriac) or from the Parthian chancery script. The exact roots of the script are difficult to determine. It was developed by members of the Mandaean faith of southern Mesopotamia to write the Mandaic language for liturgical purposes. Classical Mandaic and its descendant Neo-Mandaic are still in limited use. The script has changed very little over centuries of use.
The Mandaic name for the script is Abagada or Abaga, after the first letters of the alphabet. Rather than the traditional Semitic letter names (aleph, beth, gimel), they are known as a, ba, ga and so on.
It is written from right to left in horizontal lines. It is a cursive script, but not all letters connect within a word. Spaces separate individual words.
The Mandaic alphabet contains 22 letters (in the same order as the Aramaic alphabet) and the digraph adu. The alphabet is formally closed by repeating the first letter, a, so that it has a symbolic count of 24 letters:
|1, 24||a||?||||a||?||a||U+0840 HALQA|
|6||wa||?||||||||u||?||u, w||U+0845 USHENNA|
|10||ya||?||||i||?||i, j||U+0849 AKSA|
Unlike most other Semitic alphabets, vowels are usually written out in full. The first letter, a (corresponding to alaph), is used to represent a range of open vowels. The sixth letter, wa, is used for close back vowels (u and o), and the tenth letter, ya is used for close front vowels (i and e). These last two can also serve as the consonants w/v and y. The eighth letter corresponds to the Semitic heth, and is called eh; it is pronounced as a long i-vowel but is used only as a suffix for the third person singular. The sixteenth letter, e (Aramaic ayn), usually represents e at the beginning of a word or, when followed by wa or ya, represents initial u or i respectively.
A mark similar to an underscore (?࡚ MANDAIC VOCALIZATION MARK) can be used to distinguish vowel quality for three Mandaic vowels. It is used in teaching materials but may be omitted from ordinary text. It is only used with vowels a, wa, and ya. Using the letter ba as an example:
A dot under a consonant (?࡛ MANDAIC GEMINATION MARK) can be used to note gemination, indicating what native writers call a "hard" pronunciation. Sample words include ࡛? (ekka) 'there is', ࡛? (?enna) 'tooth', ࡛? (lebba) 'heart', and ࡛? (rabba) 'great'.
Both adu (ࡖ MANDAIC LETTER DUSHENNA) and the old ligature k? (ࡗ MANDAIC LETTER KAD) are treated as single characters in Unicode.
Postclassical and modern Mandaic use many Persian words. Various Mandaic letters can be re-purposed by placing two horizontally-aligned dots underneath (?࡙ MANDAIC AFFRICATION MARK). This idea is comparable to the four novel letters in the Persian alphabet, allowing the alphabet to be used to represent foreign sounds (whether affrication, lenition, or another sound):
The Semitic alphabet contains 22 letters. In order to bring this number to 24, the number of hours in a day, adu was added and a was repeated as the last letter of the Mandaic alphabet. Without this repetition the alphabet would be considered incomplete for magical purposes.
The Mandaic alphabet was added to the Unicode Standard in October, 2010 with the release of version 6.0.
The Unicode block for Mandaic is U+0840–U+085F:
