ஊ-row (கூ ஙூ சூ …)
Tap any tile to hear the compound letter.
The ஊ-row compound letters — uyirmey (உயிர்மெய்) — are formed by joining each of the 18 pure consonants with the vowel ஊ. The result: 18 single glyphs that each carry one consonant and one vowel sound.
How they’re formed
க் + ஊ = கூ (kū) · ங் + ஊ = ஙூ (ṅū) · ச் + ஊ = சூ (cū)
… and so on for all 18 consonants. The vowel sign ூ attaches to every consonant in the same way.
