Consonant letters with multiple allophones are starred (*):
- The letter <n> is velar before a velar stop or <w>, palatal before <y> and coronal otherwise.
- The letter <j> is a fricative in coda position and an affricate in onset position.
- The letter <c> is a fricative in coda position and an affricate in onset position, except after <s>
The geminates [t:S)] and [S:] are written <cc> and <sc>, respectively.
The geminate [r:] is written <rr> and is phonemic only between vowels.

The diphthongs are <au>, <ai>, <oi>, <eu>, <ei>, and <ou>, of which only the first is common.
In addition to their use as consonant letters, <y> and <w> appear instead of <i> and <u> in unstressed penults.

Note: <ay> and <ey> appear in the vocabulary instead of <ai> and <ei>; this should be fixed. However, <y> and <w> make more sense than <i> and <u> in diphthongs.

Epenthesis

In pronunciation, but never in writing, an epenthetic vowel may occur before or after a consonant to make pronunciation easier.

Syllable Structure

A TIAL syllable's nucleus is usually a simple vowel, sometimes a diphthong. The coda, if it occurs, is a single consonant. The onset, if it occurs, is a single consonant or a cluster; a leftover <s> may occur initially before certain consonants and clusters.

Stress

Most TIAL words stress the penult. Note that syllable definition is based strictly on the written form.
