Distribution
The statistic vowel spread is fairly typical cross-linguistically. Counting each root once, 32% of vowels are /a/, 25% /i/, /e/ and /o/ a bit over 15% each, and 10% are /u/. 20% of roots are vowel initial. The usage frequency in a 10kB sample of texts was slightly more skewed: 34% /a/, 30% /i/, 15% each /e/ and /o/, and 6% /u/.[13]
Of the syllable-initial consonants, /l/ is the most common, at 20% total; /k, s, p/ are over 10%, then the nasals /m, n/ (not counting final N), with the least common, at little more than 5% each, being /t, w, j/.
The high frequency of /l/ and low frequency of /t/ are somewhat unusual among the world's languages. The fact that /l/ occurs in the grammatical particles la, li, ala suggests that its percentage would be even higher in texts; the text-based stats cited above did not specifically consider initial consonants, but indicate that /l/ was about 25%, while /t/ doubled its frequency to just over 10% (/k/, /t/, /m/, /s/, /p/, respectively, ranged over 12% to 9% each, with /n/ unknown, and the semivowels /j/ and /w/ again coming in last at 7% each).
Syllable structure
All syllables are of the form (C)V(N), that is, optional consonant + vowel + optional final nasal, or V, CV, VN, CVN. As in most languages, CV is the most common syllable type, at 75% (counting each root once). V and CVN syllables are each around 10%, while only 5 words have VN syllables (for 2% of syllables). In both the dictionary and in texts, the ratio of consonants to vowels is almost exactly one-to-one.
Most roots (70%) are disyllabic; about 20% are monosyllables and 10% trisyllables. This is a common distribution, and similar to Polynesian.
