Khmer Letter Ro

Use the Khmer key; for clusters, type base, coeng, then រ. For the standalone letter, press its assigned key on a Khmer keyboard layout; the physical key depends on the layout.

To enter a subjoined consonant, type the preceding base consonant, the coeng sign, and រ in that order. Coeng signals that the next consonant is subjoined; it is not displayed as a separate mark. Subjoined រ wraps left and beneath the consonant before it.

Khmer writing developed from Brahmi-related South Indian models; early regional inscriptions show forms resembling Pallava, a South Indian script. The inscription catalogued as K. 600, from Angkor Borei, is the earliest dated inscription in Khmer script; it dates to 611 CE. Early inscriptions record religious dedications, offerings, land, servants and royal orders. An inscription at Prasat Ta Muen Thom, dated 1013 CE, records these temple and royal matters together. Thai script adapted directly from Khmer in the 13th century; Lao script descends from an older Khmer form.
