Ā (Indic)

Template:Infobox Indic letter

Ā is a vowel of Indic abugidas. In modern Indic scripts, Aa is derived from the early "Ashoka" Brahmi letter after having gone through the Gupta letter . As an Indic vowel, "Ā" comes in two normally distinct forms: 1) as an independent letter, and 2) as a vowel sign for modifying a base consonant. Bare consonants without a modifying vowel sign have the inherent short "A" vowel.

Aryabhata used Devanagari letters for numbers, very similar to the Greek numerals, even after the invention of Indian numerals. The "Ā" modifier could be used to indicate a consonant's base value, although the unmodified consonant had this value as well. The independent vowel letter आ was not used to indicate any numeric value in the Aryabhata system.

Historic Ā

There are three different general early historic scripts - Brahmi and its variants, Kharoṣṭhī, and Tocharian, the so-called slanting Brahmi. Aa as found in standard Brahmi, was a simple geometric shape, with variations toward more flowing forms by the Gupta . Like all Brahmic scripts, Tocharian Ā has an accompanying vowel mark for modifying a base consonant. In Kharoṣṭhī, the only independent vowel letter is for the inherent A. All other independent vowels, including Ā are indicated with vowel marks added to the letter A.

Brahmi Ā

The Brahmi letter Ā , is probably derived from the Aramaic Alef , and is thus related to the modern Latin A and Greek Alpha. Several identifiable styles of writing the Brahmi Aa can be found, most associated with a specific set of inscriptions from an artifact or diverse records from an historic period. As the earliest and most geometric style of Brahmi, the letters found on the Edicts of Ashoka and other records from around that time are normally the reference form for Brahmi letters, with vowel marks not attested until later forms of Brahmi back-formed to match the geometric writing style.

Notes

Character encodings of Ā

Most Indic scripts are encoded in the Unicode Standard, and as such the letter Ā in those scripts can usually be represented in plain text with a single codepoint. However, if the letter A is used as a consonant or a vowel support, the letter Ā is usually encoded as letter A plus vowel sign Ā. Ā from several modern-use scripts can also be found in legacy encodings, such as ISCII. Template:Indic encoding
