Ødiláïffe

Consonants
* The alveolar trill and lateral approximant are in complimentary distribution, with /r/ appearing in syllable onset, and /l/ in syllable coda and intervocallically.
 * Velar consonants become labialised before rounded vowels.
 * Nasal consonants become voiceless word-initially.
 * Plosives and affricates become devoiced word-finally.
 * All consonants except approximants and affricates can be geminated.

Vowels
* The mid central and open back vowels vary in roundedness to agree with the preceding vowel. Mid central vowels are rounded if in the first syllable of a word; open back vowels are unrounded if in the first syllable of a word.
 * Back vowels become rounded after labial and labialised velar consonants.
 * All vowels can be geminated. Vowels can take on three phonemic lengths: short, long and extra-long.

Diphthongs
The possible dipthongs in Ødilaaife are /ɑi/, /ɑɯ/, /ɒy/, and /ɒu/, written «ai, aw, ay, au» respectively. Diphthongs can be geminated. Ungeminated diphthongs are long, and geminated diphthongs are extra-long. In geminated diphthongs, the first component is the one that becomes lengthened.

Alphabet
* Geminant consonants are written as double letters. Long vowels are written doubled, and extra-long vowels are written tripled.

Codas can be a single consonant, a geminate consonant or an affricate, but they may not be approximants or consonant clusters.
