Ra (Indic)


Ra is a consonant of Indic abugidas. In modern Indic scripts, Ra is derived from the early "Ashoka" Brahmi letter after having gone through the Gupta letter. Most Indic scripts have differing forms of Ra when used in combination with other consonants, including subjoined and repha forms. Some of these are encoded in computer text as separate characters, while others are generated dynamically using conjunct shaping with a virama.

Āryabhaṭa numeration

used Devanagari letters for numbers, very similar to the Greek numerals, even after the invention of Indian numerals. The values of the different forms of र are:
There are three different general early historic scripts - Brahmi and its variants, Kharoṣṭhī, and Tocharian, the so-called slanting Brahmi. Ra as found in standard Brahmi, was a simple geometric shape, with variations toward more flowing forms by the Gupta. The Tocharian Ra had an alterante Fremdzeichen form,. The third form of ra, in Kharoshthi was probably derived from Aramaic separately from the Brahmi letter.

Brahmi Ra

The Brahmi letter, Ra, is probably derived from the Aramaic Resh, and is thus related to the modern Latin R and Greek Rho. Several identifiable styles of writing the Brahmi Ra 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.

Tocharian Ra

The Tocharian letter is derived from the Brahmi, and has an alternate Fremdzeichen form used in conjuncts and as an alternate representation of Rä. The use of repha forms in modern Indic scripts is similar to the Fremdzeichen Ra in Tocharian.

Kharoṣṭhī Ra

The Kharoṣṭhī letter is generally accepted as being derived from the Aramaic Resh, and is thus related to R and Rho, in addition to the Brahmi Ra.

Devanagari Ra

Ra is a consonant 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 ?.

Devanagari-using Languages

In all languages, र is pronounced as or when appropriate. Like all Indic scripts, Devanagari uses vowel marks attached to the base consonant to override the inherent /ə/ vowel:
RaRiRuRrRr̄RlRl̄ReRaiRoRauR
रारिरीरुरूरृरॄरॢरॣरेरैरोरौर्

Several languages use the dotted form Rra for the sound instead of र. ऱ combines with vowel marks identically to र.

Conjuncts with र

Devanagari exhibits conjunct ligatures, as is common in Indic scripts. In modern Devanagari texts, most conjuncts are formed by reducing the letter shape to fit tightly to the following letter, usually by dropping a character's vertical stem, sometimes referred to as a "half form". Some conjunct clusters are always represented by a true ligature, instead of a shape that can be broken into constituent independent letters. Vertically stacked conjuncts are ubiquitous in older texts, while only a few are still used routinely in modern Devanagari texts. The use of ligatures and vertical conjuncts may vary across languages using the Devanagari, with Marathi in particular preferring the use of half forms where texts in other languages would show ligatures and vertical stacks.
When in conjuncts with other letters, र takes on several different forms, the most important of which are Repha and Rakar.
Repha is used to indicate that a conjunct begins with "R". It is crescent shape attached atop the headline of the rest of the conjunct at the right, immediately above the vertical stem, if present. The other members of the conjunct ignore Repha for shaping, combining with the other members of the conjunct to form ligatures or stacked conjuncts normally.
Rakar is used to indicate a consonant conjunct ending in "Ra". It is an upward-pointing wedge shape that is found either centered below the rest of the conjunct, or tilted to the right and integrated with the bottom of the stemline. Like with Repha, the rest of the conjunct ignores Rakar for shaping, except for minor alteration of the bottom of any stemline.
The third conjunct form of Ra is the so-called Eyelash Ra. It resembles a half-form in retaining the head line, with a shape below that connects to the following letter, but this remaining eyelash shape does not resemble either र or ऱ. The eyelash Ra is used in Nepali and Marathi texts instead of Repha for an initial "R" sound in a conjunct. Even though those languages both use the dotted Ra ऱ, eyelash Ra is the default form of Ra + Virama in Unicode for backwards compatibility, and the Repha form is mapped individually as a ligature with each other Devanagari consonant.

Devanagari Rakar

Several conjuncts have both Repha and Rakar forms:

Bengali Ra

The Bengali script র is derived from the Siddhaṃ, and is marked by a similar horizontal head line, but less geometric shape, than its Devanagari counterpart, र. The inherent vowel of Bengali consonant letters is /ɔ/, so the bare letter র will sometimes be transliterated as "ro" instead of "ra". Adding okar, the "o" vowel mark, gives a reading of /ro/.
Like all Indic consonants, র can be modified by marks to indicate another vowel than its inherent "a".

র in Bengali-using languages

র is used as a basic consonant character in all of the major Bengali script orthographies, including Bengali and Assamese.

Conjuncts with র

Bengali র exhibits conjunct ligatures, as is common in Indic scripts. Much like other Indic scripts, Bengali র also rarely appears in conjuncts in full form, and has special unrelated graphic forms for both initial and trailing র in conjuncts called Repha and Ra phala.

Bengali Ra-phala

The letter র has a special form when used as the last letter of a conjunct called "Ra phala". This reduced form of র is appended to the bottom of a letter or conjunct. Both Ya and Va have a similar "phala" trailing form. Ra-phala and Ya-phala can be found together in many conjuncts.

Bengali Repha

Unlike other letters, র also has a special form when used as the initial letter of a conjunct called "Repha". This reduced form of র on top of the following letter or conjunct. Repha can be found in combination with Ra-phala, Ya-phala and Va-phala in many conjuncts.
