Origin Mature Brahmi is securely attested in the edicts of Ashoka in the middle of the third century BCE, and the script could be read again only after James Prinsep worked out its values in 1837
Ai is the second grade of the front vowel series, always long and always heavy in metre. The grammatical tradition describes a ladder of strengthening in which i becomes e and e becomes ai, and the same ladder runs from u through o to au, which is why the four stand together at the end of the vowels in the Brahmi order rather than beside the simple vowels they are built from. Ai holds twelfth place. Its mark is written above the consonant sign and is distinguished from the mark for e by a doubling, so the shape on the page reflects the sound's standing as one step further along the same series. In the Prakrit of the inscriptions the compound vowels are less stable than in Sanskrit, and forms with e or o where the older language had ai or au are ordinary.
Facts
Disputed
Origin PeriodMany epigraphists derive Brahmi from a Semitic prototype, most often Aramaic, adapted in the centuries before the Mauryan empire 2Tradition: Indian epigraphy Brahmi's ancestry is disputed among epigraphists. Richard Salomon's Indian Epigraphy (Oxford University Press, 1998) surveys two live positions on the origin of the script attested in the Ashokan inscriptions: one derives Brahmi from a Semitic prototype, most often Aramaic, adapted in the centuries before the Mauryan empire; the other holds that it developed inside India itself. The dispute turns on the corpus, since Brahmi is securely attested only from Ashoka's edicts in the middle of the third century BCE onward, first read again by James Prinsep in 1837, and no earlier specimen on either side is securely dated. Both camps compare Brahmi's letterforms against Aramaic and other Semitic scripts using the same paleographic method, and without an intermediate dated example bridging the gap between any proposed ancestor and the Mauryan era script, neither derivation has been shown to fit the evidence better than the other. Origin PeriodOthers argue for a development inside India, and with no securely dated specimen earlier than the edicts the question stays open 2Tradition: Indian epigraphy Brahmi's ancestry is disputed among epigraphists.

Origins
Origin PeriodMature Brahmi is securely attested in the edicts of Ashoka in the middle of the third century BCE, and the script could be read again only after James Prinsep worked out its values in 1837 2Tradition: Indian epigraphy Place of OriginThe Indian subcontinent. The Ashokan edicts carry the script from the Gangetic plain across the Deccan to the far south, while the northwest of the same empire wrote in Kharosthi instead 2Tradition: Indian epigraphy Origin of the NameThe letter has no traditional name of its own. It is called by the vowel it writes, and the form used here is the name the Unicode Standard gives the character 3Tradition: Modern scholarly naming of the Brahmi letters Sense of the Namethe vowel ai; twelfth letter of the Brahmi order 3Tradition: Modern scholarly naming of the Brahmi letters Transmission
Manuscript TraditionAttested from the Asokan rock and pillar edicts of the third century BCE, the earliest substantial Brahmi corpus. 2 Identity
Script TypeAn abugida: every consonant sign carries an inherent short a, which a vowel mark alters and the virama cancels, so the unit written is the syllable rather than the single sound 1Tradition: Comparative writing systems PositionTwelfth letter of the Brahmi order and the second of the compound vowels 2Tradition: Indian epigraphy How the Letter JoinsAn independent vowel letter takes no attachment. After a consonant the same vowel is written not with this letter but as a mark added to the consonant sign 1Tradition: Comparative writing systems Attributions
Associated SoundAlways long and heavy in metre; the second strengthening grade of i, one degree beyond e on the ladder the grammarians call guna and vrddhi 2Tradition: Indian epigraphy Attestation
Meaning in the Attesting SourceThe letter belongs to the received Brahmi order, and the corresponding sign in the scripts descended from Brahmi across South and Southeast Asia goes back to it 2Tradition: Indian epigraphy Learn More
The Second Grade, and What It Builds
Vrddhi is the higher of the two strengthening grades the Indian grammarians describe, and for the front series it produces this vowel. Where guna raises i to e, vrddhi raises it past e to ai, and the grade is called for by a specific set of suffixes, most notably the ones that form patronymics and adjectives of belonging. A very large part of the Sanskrit vocabulary of relation and derivation runs through that operation: the name of a descendant, the adjective naming what pertains to a place or a school, and a wide class of abstract nouns all show the vrddhi vowel where the underlying stem shows the simple one.
The result is that this letter is met most often at the head of a word rather than inside it, because the strengthening applies to the first syllable of the stem. That in turn means the independent letter, rather than the attached mark, is the form a reader sees. In the Prakrit of the Ashokan edicts the picture is different: the compound vowels are less stable in Middle Indo-Aryan, and forms with a plain e where the older language had ai are ordinary, so the letter is written far less often in the earliest inscriptions than a Sanskrit text would lead a reader to expect.
The two grades are also what makes a Sanskrit dictionary usable. Entries are listed under the root in its plain form, and a reader who meets a derived word has to strip the suffix and lower the vowel to find it. That operation is taught before anything else in the language, and this letter is one of the two vowels a beginner learns to reduce on sight. A word opening with it is very often a derivative of a root opening with the simple front vowel, and recognising the relation is the difference between reading a text and decoding it.
A Mark Built by Doubling
Brahmi writes the mark for this vowel by doubling the element used for e, so the shape on the page records the analysis the phoneticians gave the sound: one step further along the same series, written as one more of the same stroke. That is a general habit of the script rather than a single convenience. The mark for au is built on the mark for o in the same way, and the four compound vowels form a family of related shapes rather than four unrelated signs. A writing system that encodes its own phonetic analysis in the shapes is unusual, and it is one of the features that makes the Brahmi vowel series worth studying as a designed object.
The habit does not survive intact into every descendant. Some of the later scripts keep the doubling plainly visible, some fuse the two elements into a single stroke, and some rebuild the sign around a different base entirely, so the family resemblance among the compound vowels is clearer in the parent script than in several of its children. Tracking where the doubling was kept and where it was lost is one of the ordinary comparisons of Indian palaeography, and it groups the descendant scripts in ways that do not always match how they are grouped by geography.
Cross-Tradition Connections
Derived from This
Devanagari Ai descends from the Brahmi sign of the same value, through the Gupta and Nagari hands of northern India. The two alphabets align letter for letter because both are laid out in the varnamala order, the arrangement the Sanskrit phoneticians fixed by place of articulation.
Ranjana Ai continues the sign Brahmi Ai writes in the same place of the inherited varnamala. The descent is not direct: it runs through the Gupta and Siddhamatrka stages of the northern Brahmi line and then the scripts of Nepal, and it is stated from position in the order rather than from shape.
Siddham continues the Brahmi order letter for letter. The descent runs through the late Brahmi of the Gupta period and the Siddhamatrka hand that grows out of it, so this is a lineage rather than a direct copy of the older shape.
Related To
Successive grades of the same series. The vrddhi vowel stands one step above the guna vowel, and the Brahmi mark for it is built by adding to the mark for e rather than by drawing a separate shape.
Second strengthening grade. Where guna raises i to e, vrddhi raises it one step further to ai, and the two grades together account for most of the vowel changes in Sanskrit derivation.
