Ṝ is a vowel-like letter of Indic abugidas, often referred to as a "vocalic R̄". In modern Indic scripts, Ṝ is derived from the early "Ashoka" Brahmi letter . As an ostensible Indic vowel, Ṝ 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.
