Phonotactics

The ſyllable ſtructure is (C)V(N), with the ſtreſs on the primary ſyllable.
For example, aitaikanaum is OK, but imaiklaul is not.

In old Aichinau, there were ten diphthongs:
ai, au, ia, iu, iai, iau, ua, uai, uau, and ui pronounced like it was written, except for i-diphths and u-diphths that ſtarted with j (in IPA) and w.
Now, ai and au are pronounced e and o, including the triphthongs, pronounced je, jo, we, and wo.
One thing to note is at the end of a word, au is pronounced like u.

For allophones, the moſt notable example is s.
If i comes after s, s is pronounced like /ʃ/.
Alſo, sui is pronounced /si/.
