Syllabic structure The Arem language makes use of both monosyllabic words and sesquisyllabic words. It is estimated that 55–60% of the Arem language's consists of sesquisyllabic words. This is much higher than the majority of other Vietic languages that typically utilize sesquisyllables in only 35-40% of their lexicon, if the particular language contains any sesquisyllables at all.
Suprasegmentals Arem's vowel inventory is split into two series of voice-type
registers. Series 2 is characterized by a low-breathy register phonation. In syllables ending in voiced finals (/Ø, w j l m n ɲ ŋ/), this register involves a contrast between a low-breathy modal tone and a glottalized tone marked by a weak glottal stop. Syllables ending in /-h/ produce a tone corresponding to the Vietnamese
huyền, while those checked by voiceless stops (/-p -t -c -k/) yield low-pitch outcomes corresponding to the tone
nặng. This registral opposition is the result of vowel splitting in two series from a single proto-vowel. Series 1 is characterized by a high-clear register phonation. Within syllables containing voiced finals, this series maintains a contrast between a high, clear, unmarked tone and a high, glottalized, slightly raising tone. Clear vowels in syllables ending in /-h/ correspond to the Vietnamese tone
hỏi. In checked syllables ending in voiceless stops, vowels of this series yield high-pitch outcomes corresponding to the Vietnamese tone
sắc. The combination of the contrast between clear and breathy phonation with glottalization in unchecked syllables forms the four-tone prosodic system:
