Aiueo Order
Syllabary Order
noun
This is a little confusing for someone who didn't grow up with the Japanese language. You have fifty sounds. Then, they're in a certain order. So, these fifty sounds are the Japanese syllabary. That's hiragana / katakana, probably from back in the day when there were more sounds than there are now. So, the "fifty sounds in order" makes up aiueo order, where the "aiueo" is あいうえお representing the five columns.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
町名は五十音順にならんでいます。
The town names are listed in aiueo order.
僕の名前は、五十音順だといつも一番最初になります。
My name is always first in aiueo order.
リストは好き順とかじゃなく、ただの五十音順なので、悪しからず。
The list is not in order of preference or anything, just in aiueo order, so please don't be put off by that.
