As a final sound, "m" adapts to the succeeding word as a nasal sound (Anusvara, ṁ).

  • Final "m" before consonants becomes an Anusvāra (ṁ). (spelled separately, together for compound words)
    Optionally before consonants also the class nasal. (spelled together)
  • Final "m" before vowels stay "m". (spelled together)
