Avestan Ke 𐬐

The sound is a plain k, made by closing the back of the tongue against the soft palate and releasing it. It stands first among the consonants because the alphabet orders them by where in the mouth the sound is made, and its compilers chose to begin at the back. The velar letters stand at the head of the consonant section. The alphabet orders its consonants by where in the mouth the sound is made, beginning at the soft palate and working forward, so the k, the fricatives that go with it and the voiced sounds that answer to them all fall together at the start.

Within the series the plain sound comes first and the modified ones follow. It stands seventeenth in the alphabet as a whole and first of the thirty-eight consonants, between Avestan Uu and Avestan Xe. That position is not arbitrary. The sequence follows a scheme, vowels before consonants and consonants by place of articulation, and each letter's place in it is a statement about the sound. The tradition calls the script din dabireh, the religion writing. It served the Avesta and very little else, and the shape of its letter list follows the sounds of that one language rather than any general requirement of writing in Sasanian Iran. A reciter using this alphabet is not being taught the text. The priesthood that used it already knew the Avesta by heart, and the page served as a check on memory rather than as a substitute for it, which is why the script records fine detail a learner would never need.

The consonant section opens at the back of the mouth and works forward, an ordering derived from an analysis of how sounds are made rather than from any inherited letter sequence. The Aramaic order that lies behind so much of what was written in the region has been set aside entirely. The shapes come from Pahlavi and the inventory does not. Whoever assembled this alphabet worked from an analysis of the recitation, added signs where the parent hand had none, and ordered the result by place of articulation instead of by the letter sequence that lay behind everything else written in Iran at the time.

Modern editions preserve the distinctions the manuscripts make, including the ones that look redundant, and transliterate them with accents, dots and length marks so that nothing collapses on the page. The apparatus of marks in a scholarly Avestan text is a direct consequence of how many separate signs the alphabet carries. In the digital record the letter is encoded at U+10B10 AVESTAN LETTER KE. The Avestan block sits wholly in the supplementary planes, and every letter in it takes four bytes in the encoding most of the web runs on. That is the practical reason Avestan text is still uncommon online, and why a page carrying it depends on the reader having a font that covers the range. Zoroastrianism is a living religion with a small community, and the Avesta is its liturgy rather than its archive. The letters of this alphabet are therefore not an antiquarian matter. They record sounds a priest is still expected to produce.
