Ā is a vowel of Indic abugidas. In modern Indic scripts, Aa is derived from the early "Ashoka" Brahmi letter Ā 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.

Āryabhaṭa numeration edit

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.[1]

Historic Ā edit

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 edit

The Brahmi letter Ā , is probably derived from the Aramaic Alef , and is thus related to the modern Latin A and Greek Alpha.[2] 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.[3] 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.

Tocharian Ā edit

The Tocharian letter is derived from the Brahmi . Unlike some of the consonants, Tocharian vowels do not have a Fremdzeichen form.

Kharoṣṭhī Ā edit

The Kharoṣṭhī letter Ā is indicated with the vowel length mark . As an independent vowel, Ā is indicated by adding this vowel mark to the independent vowel letter A .

Devanagari Ā edit

Devanagari independent Ā and Ā vowel sign.

Ā () is a vowel of the Devanagari abugida. It ultimately arose from the Brahmi letter , after having gone through the Gupta letter . Letters that derive from it are the Gujarati letter , and the Modi letter 𑘁.

Devanagari Using Languages edit

The Devanagari script is used to write the Hindi language, Sanskrit and the majority of Indo-Aryan languages. In most of these languages, आ is pronounced as [ā]. Like all Indic scripts, Devanagari vowels come in two forms: an independent vowel form for syllables that begin with a vowel sound, and a vowel sign attached to base consonant to override the inherent /ə/ vowel.

Bengali Ā edit

Bengali independent Ā and Ā vowel sign.

Ā () is a vowel of the Bengali abugida. It is derived from the Siddhaṃ letter , and is marked by a similar horizontal head line, but less geometric shape, than its Devanagari counterpart, आ.

Bengali Script Using Languages edit

The Bengali script is used to write several languages of eastern India, notably the Bengali language and Assamese. In most languages, আ is pronounced as [ā]. Like all Indic scripts, Bengali vowels come in two forms: an independent vowel form for syllables that begin with a vowel sound, and a vowel sign attached to base consonant to override the inherent /ɔ/ vowel.

Gujarati Ā edit

Gujarati independent Ā and Ā vowel sign.

Ā () is a vowel of the Gujarati abugida. It is derived from the Devanagari Ā , and ultimately the Brahmi letter .

Gujarati-using Languages edit

The Gujarati script is used to write the Gujarati and Kutchi languages. In both languages, આ is pronounced as [ā]. Like all Indic scripts, Gujarati vowels come in two forms: an independent vowel form for syllables that begin with a vowel sound, and a vowel sign attached to base consonant to override the inherent /ə/ vowel.

Telugu Ā edit

Telugu independent vowel and vowel sign Ā.

Ā () is a vowel of the Telugu abugida. It ultimately arose from the Brahmi letter . It is closely related to the Kannada letter . Like in other Indic scripts, Telugu vowels have two forms: and independent letter for word and syllable-initial vowel sounds, and a vowel sign for changing the inherent "a" of Telugu consonant letters. Vowel signs in Telugu can interact with a base consonant in one of three ways: 1) the vowel sign touches or sits adjacent to the base consonant without modifying the shape of either 2) the vowel sign sits directly above the consonant, replacing its v-shaped headline, 3) the vowel sign and consonant interact, forming a ligature.

Telugu Ā vowel sign on క, ఖ, గ, ఘ & ఙ: Kā, Khā, Gā, Ghā and Ngā. Note that how the vowel sign interacts with the base consonant is dependent on the location of the headline, the absence of a headline, and the presence of a tail to attach to.

Malayalam Ā edit

Malayalam independent vowel and vowel sign Ā.

Ā () is a vowel of the Malayalam abugida. It ultimately arose from the Brahmi letter , via the Grantha letter aa. Like in other Indic scripts, Malayalam vowels have two forms: an independent letter for word and syllable-initial vowel sounds, and a vowel sign for changing the inherent "a" of consonant letters. Vowel signs in Malayalam usually sit adjacent to its base consonant - below, to the left, right, or both left and right, but are always pronounced after the consonant sound.

Odia Ā edit

Odia independent and vowel sign Ā

Ā () is a vowel of the Odia abugida. It ultimately arose from the Brahmi letter , via the Siddhaṃ letter aa. Like in other Indic scripts, Odia vowels have two forms: an independent letter for word and syllable-initial vowel sounds, and a vowel sign for changing the inherent "a" of consonant letters. Vowel signs in Odia usually sit adjacent to its base consonant - below, to the left, right, or both left and right, but are always pronounced after the consonant sound. No base consonants are altered in form when adding a vowel sign, and there are no consonant+vowel ligatures in Odia.

Kaithi Ā edit

Kaithi independent vowel and vowel sign Ā.

Ā (𑂄) is a vowel of the Kaithi abugida. It ultimately arose from the Brahmi letter , via the Siddhaṃ letter aa. Like in other Indic scripts, Kaithi vowels have two forms: an independent letter for word and syllable-initial vowel sounds, and a vowel sign for changing the inherent "a" of consonant letters. Vowel signs in Kaithi usually sit adjacent to its base consonant - below, to the left, right, or both left and right, but are always pronounced after the consonant sound. No base consonants are altered in form when adding a vowel sign, and there are no consonant+vowel ligatures in Kaithi.

Comparison of Ā edit

The various Indic scripts are generally related to each other through adaptation and borrowing, and as such the glyphs for cognate letters, including Ā, are related as well.

Notes
  1. ^ The middle "Kushana" form of Brahmi is a later style that emerged as Brahmi scripts were beginning to proliferate. Gupta Brahmi was definitely a stylistic descendant from Kushana, but other Brahmi-derived scripts may have descended from earlier forms.
  2. ^ Tocharian is probably derived from the middle period "Kushana" form of Brahmi, although artifacts from that time are not plentiful enough to establish a definite succession.
  3. ^ Pyu and Old Mon are probably the precursors of the Burmese script, and may be derived from either the Pallava or Kadamba script
  4. ^ May also be derived from Devangari (see bottom left of table)
  5. ^ The Origin of Hangul from 'Phags-pa is one of limited influence, inspiring at most a few basic letter shapes. Hangul does not function as an Indic abugida.
  6. ^ Although the basic letter forms of the Canadian Aboriginal Syllabics were derived from handwritten Devanagari letters, this abugida indicates vowel sounds by rotations of the letter form, rather than the use of vowel diacritics as is standard in Indic abugidas.
  7. ^ May also be derived from Ranjana (see above)
  8. ^ Masaram Gondi acts as an Indic abugida, but its letterforms were not derived from any single precursor script.


Character encodings of Ā edit

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.
