Raku

A raku is a Toaq phonology concept similar to a syllable. Every word is made of multiple raku, and every prefix is exactly one raku long.

For the most part, raku consist of

• a consonant except q, so one of b c ch d f g h j k l m n p r s t ꝡ z ')
• a vowel or diphthong (a e ı o u aı ao eı oı)
• optionally another vowel or diphthong, if what precedes isn't a diphthong
• optional q or m, if what precedes isn't a diphthong

There are some restrictions:

• No double vowels (reeı is invalid)
• nhı ꝡı ꝡu ae au ou are all disallowed

Whether something is a valid raku doesn't depend on its tone: fîeq is one raku but three syllables, /fi˧˥ˈiː˥˩ɛŋ˩/.
