Tones
Sila has three lexical tonemes and two grammatical tonemes.

Phonotactics
All consonants can occur as onsets, with /m/ able to form a syllabic nasal.

/j/ and /l/ may occur as medials, but /j/ only after bilabial and velar stops and /m/, and /l/ only after bilabial stops and /m/.

Unvoiced stops and nasals can occur as codas, but these are only found in words recently borrowed from Lao
