'''Au''' is a vowel of Indic abugidas. In modern Indic scripts, Au is derived from the middle "[[Kushana]]" Brahmi letter [[Image:Gupta ashoka au.svg|13px|ng]], and the [[Gupta script|Gupta]] letter [[File:Gupta allahabad au.svg|13px]]. As an Indic vowel, Au 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 "A" vowel.

==Āryabhaṭa numeration==

{{further|Āryabhaṭa numeration}}

[[Aryabhata]] used Devanagari letters for numbers, very similar to the [[Greek numerals]], even after the invention of [[Indian numerals]]. The  ौ sign was used to modify a consonant's value {{e|16}}, but the vowel letter औ did not have an inherent value by itself.<ref name="Ifrah">{{cite book|last=Ifrah|first=Georges|title=The Universal History of Numbers. From Prehistory to the Invention of the Computer|year=2000|publisher=John Wiley & Sons|location=New York|isbn=0-471-39340-1|pages=447–450}}</ref>

==Historic Au==
There are three different general early historic scripts - [[Brahmi script|Brahmi]] and its variants, [[Kharosthi|Kharoṣṭhī]], and [[Tocharian alphabet|Tocharian]], the so-called ''slanting Brahmi''. Au was not found in the earliest forms of [[Brahmi]], but was found in the more flowing forms the Kushana [[Image:Gupta ashoka au.svg|13px|Au]] and Gupta [[Image:Gupta allahabad au.svg|13px|Au]]. Like all Brahmic scripts, Tocharian Au [[Image:Tocharian letter au.gif|18px|Au]] 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 Au are indicated with vowel marks added to the letter A.

===Brahmi Au===

The Brahmi letter Au, is based on the [[O (Indic)#Brahmi O|letter O]] which was [[Brahmi script#origin|probably derived]] from the  Aramaic [[Waw (letter)|Waw]] [[File:Waw.svg|13px]]. That would make it related to the modern Latin [[F]], [[V]], [[U]], [[W]], [[Y]] and Greek [[Upsilon]].<ref name="Buhler">{{cite web |last1=Bühler |first1=Georg |title=On the Origin of the Indian Brahmi Alphabet |url=https://archive.org/details/onoriginofindian00bhuoft/page/n3/mode/2up |website=archive.org |publisher=Karl J. Trübner |accessdate=10 June 2020}}</ref> Several identifiable styles of writing the Brahmi Au can be found, most associated with a specific set of inscriptions from an artifact or diverse records from an historic period.<ref>[[:File:Brahmi script consonants according to James Prinsep March 1838.jpg|Evolutionary chart]], Journal of the Asiatic Society of Bengal Vol 7, 1838 [https://archive.org/stream/journalofasiatic775asia#page/n101]</ref> 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, but only being found in later styles, the reference form of Brahmi Au is back-formed from later styles to match the geometric writing style.

===Tocharian Au===

The Tocharian letter [[Image:Tocharian letter au.gif|25px|Au]] is derived from the Brahmi [[Image:Gupta ashoka au.svg|13px|Au]]. Unlike some of the consonants, Tocharian vowels do not have a [[Tocharian alphabet#Script|Fremdzeichen]] form.

===Kharoṣṭhī Au===

The Kharoṣṭhī letter Au is indicated with the [[O (Indic)#Kharoṣṭhī O|O]] vowel mark [[File:Буква O (залежний знак). Письмо кхароштхі. Kharoshthi vowel sign O.svg|15px|Au]] plus the vowel length mark [[File:Довгий голосний (залежний знак). Письмо кхароштхі. Kharosthi vowel length mark.svg|15px]]. As an independent vowel, Au is indicated by adding the vowel marks to the independent vowel letter [[A (Indic)#Kharoṣṭhī A|A]] [[File:Буква А (незалежний знак). Письмо кхароштхі. Kharoshthi letter A.svg|15px|A]].

'''Au''' ('''ओ''') is a vowel of the [[Devanagari]] [[abugida]]. It ultimately arose from the [[Brahmi]] letter [[Image:Brahmi au.svg|13px|Au]], after having gone through the [[Gupta script|Gupta]] letter [[File:Gupta allahabad au.svg|13px|Au]]. Letters that derive from it are the [[Gujarati script|Gujarati]] letter '''ઔ''', and the [[Modi alphabet|Modi]] letter 𑘍.

===Devanagari Using Languages===
The Devanagari script is used to write the [[Hindi language]], [[Sanskrit]] and the majority of  [[Indic languages]]. In most of these languages, ओ is pronounced as {{IPA-hi|au|}}. 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. <!-- In addition to the standard vowel sign, X forms a unique ligature when combined with the consonant X:

'''Au''' ('''ঔ''') is a vowel of the [[Bengali script|Bengali]] [[abugida]]. It is derived from the [[Siddhaṃ]] letter [[Image:Siddham au.svg|13px|Au]], and is marked by the lack of horizontal head line and less geometric shape than its Devanagari counterpart, ओ.

===Bengali Script Using Languages===
The Bengali script is used to write several languages of eastern India, notably the [[Bengali language]] and [[Assamese language|Assamese]]. In most languages, ঔ is pronounced as {{IPA-bn|au|}}. 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. <!-- In addition to the standard vowel sign, X forms a unique ligature when combined with the consonant X:

'''Au''' ('''ઔ''') is a vowel of the [[Gujarati script|Gujarati]] [[abugida]]. It is derived from the Devanagari Au [[Image:Devanagari au.svg|13px|au]], and ultimately the [[Brahmi]] letter [[Image:Brahmi au.svg|13px|au]].

===Gujarati-using Languages===
The Gujarati script is used to write the [[Gujarati language|Gujarati]] and [[Kutchi language|Kutchi]] languages. In both languages, ઔ is pronounced as {{IPA-gu|au|}}. 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.

'''Au''' ('''ఔ''') is a vowel of the [[Telugu script|Telugu]] [[abugida]]. It ultimately arose from the [[Brahmi]] letter [[Image:Brahmi au.svg|13px|Au]]. It is closely related to the [[Kannada script|Kannada]] letter '''ಔ'''. 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.

'''Au''' ('''ഔ''') is a vowel of the [[Malayalam script|Malayalam]] [[abugida]]. It ultimately arose from the [[Brahmi]] letter [[Image:Brahmi au.svg|13px|Au]], via the [[Grantha script|Grantha]] letter [[Image:Grantha vowel Au.svg|x15px|Au]] ''au''. 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.

'''Au''' ('''ଔ''') is a vowel of the [[Odia script|Odia]] [[abugida]]. It ultimately arose from the [[Brahmi]] letter [[Image:Brahmi au.svg|13px|Au]], via the [[Siddhaṃ script|Siddhaṃ]] letter [[Image:Siddham au.svg|x15px|Au]] ''au''. 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.
