Ihazon Dialects
Ihazon has a few geolects--geographical dialects--that are distinct for each city. They are subtle changes in pronunciation, spelling and occasionally structure in the language. The wiki is written in Standard, which is based in Langenthalan.
Langenthalan
Spelling
Langenthalan is the dialect of Langenthal. Its most distinct feature is its lack of -ian; instead Langenthalers use -an. Since Standard is based on Langenthalan, this is the suffix used on the wiki.
In broad Langenthalan, many words may have some their 'i's cut if it doesn't majorly change how the word is pronounced. Thoirian becomes Thoiran, foreign becomes foregn, humiliation becomes humilaton, etc. Pronounciation is more or less the same, but will cut more 'i's the broader the dialect is.
Pronounciation
The most major pronunciation difference is 'i's, which unlike anywhere else is pronounced ee instead of ai. This means Ihazon is pronounced ee-azon. Another example is Nozahi, pronounced noza-ee. Note how the 'h' also disappears.
Some Langenthalers turn -ing into a sort of -en, so walking will sound like walk-en.
Settian
Setters are very, very concerned with using -ian, especially when referring to their dialect, settian. This is why even the wiki makes an exception for this.
Settian is mostly British in nature, and Setters frequently use slang not seen anywhere else in Ihazon. They are also the only city to pronounce Ihazon with ai instead of ee.
