Avestan I: The Letter in the Avestan Alphabet

The sound is a short close front i, the tongue high and forward and the lips spread. It is the vowel of English machine, cut short. Every vowel in this alphabet is a letter in its own right, standing on the line and taking its turn between the consonants. That is not how the writing it grew out of worked, where a reader supplied much of the vowelling from knowledge of the word, and it is not how the Indic scripts of the same centuries worked either, where vowels hung as marks above and below a consonant sign. Avestan writes them out. It stands thirteenth in the alphabet as a whole and thirteenth of the sixteen vowel letters, between Avestan Oo and Avestan Ii.

The order is the work of the people who devised the alphabet rather than an inheritance from anywhere, and reading the list straight through recovers the analysis they were working from. The Avestan alphabet was made for one text. That is unusual, and it explains a repertoire far larger than the languages around it needed. A script serving letters, accounts and contracts can afford to let two sounds share a shape, because context recovers the sense. A script serving a recitation cannot, because there the sound is the thing being preserved. Fifty-four letters is a large inventory by any standard and larger than any script in use around it. The number is less a measure of the language's complexity than of how much of the recitation the compilers decided the page ought to carry.
