Grammar Rule in 30 Seconds
Low-class consonants follow a specific tone pattern based on syllable type and tone marks.
- Dead syllables (short vowel/stop ending) with no mark = High tone (e.g., 'ka').
- Live syllables (long vowel/sonorant ending) with no mark = Mid tone (e.g., 'ma').
- Tone marks shift the pitch: 'Mai Ek' makes it Falling, 'Mai Tho' makes it High.
