What is a Lonsum Iyek (ꯂꯣꯟꯁꯨꯝ ꯏꯌꯦꯛ)?

In linguistics, a syllable coda is a consonant that comes at the very end of a syllable. In many Indian scripts, a Virama or Halant stroke is used to cancel out the inherent vowel of a consonant.

In Meitei Mayek, however, there is a dedicated, elegant set of 8 special characters called Lonsum Iyek (ꯂꯣꯟꯁꯨꯝ ꯏꯌꯦꯛ). The word Lonsum translates to "syllable-closing" or "word-ending". When a Lonsum character is written, it carries zero inherent vowel and can only appear at the end of a syllable or word.


The 8 Lonsum Characters

Each Lonsum character is derived directly from its parent Iyek Ipee letter, with a simplified visual form:

ꯉ (Ngou)ꯡNgou Lonsum-ng (/ŋ/)ꯌꯥꯡ (yang - back / fast)
ꯏ (I)ꯢI Lonsum-i (diphthong final /i̯/)ꯂꯥꯏ (lai - god / easy)

Phonetic Nuance: Unreleased Stops

A vital characteristic of spoken Manipuri is that syllable-final plosives (ꯛ, ꯞ, ꯠ) are unreleased (checked stops).

For example, when pronouncing ꯃꯤꯠ (Mit - eye), the tongue touches the alveolar ridge behind the teeth to form the 't' sound, but the breath is not released with a puff of air. This gives Manipuri speech its distinct rhythmic cadence.


Common Mistakes to Avoid

  • Do not place a Lonsum at the beginning of a word: A Lonsum like ꯛ or ꯟ can never begin a syllable. It must always follow a base consonant or vowel.
  • Do not attach vowel diacritics (Chejap) to a Lonsum: Lonsum characters are vowel-less by definition; attaching a vowel diacritic to a Lonsum is grammatically invalid.
