Rha (Ԗ ԗ; italics:
Ԗ ԗ) is a letter of the Cyrillic script. It looks like a cross-digraph of the Cyrillic letters Er (Р р) and Kha (Х х), but it is not a composable ligature.Rha was used in the alphabet used in the 1920s for the Moksha language, where it represented the voiceless alveolar trill pronounced as //r̥//, like the rh in Welsh.[1]
