Have you ever wondered what Koitsu, Soitsu, Aitsu, and Doitsu mean? In this article, we will look at the meaning of each of these words, their origin, and usage.

You may not have noticed, but these four expressions are part of the Kosoado. In other words, these expressions have similar meanings but indicate position; they are demonstrative pronouns.

What Does Yatsu Mean?

Before we talk about the meaning of Aitsu, Doitsu, Koitsu, and Soitsu, we need to understand what this itsu means. In fact, this ending is yatsu [奴].

The word [奴] means companion, guy, and individual. The word yatsu is quite generic and can refer to a person or thing.

Speaking a little about the ideogram yakko [奴], its origin refers to a servant of a samurai family during the Edo period. It can mean slave, servant, and companion.

This expression can end up conveying the idea of someone generic or of low social class. Just imagine someone saying: that guy, this guy, it seems a bit informal, sometimes it can be offensive, but it is not in most cases.

We can define Yatsu as follows:

  • A word that refers to things in a careless way;
  • A word that humiliates people;
  • A word that expresses affection for the current person (He is the guy!);
  • A word that despises birds and beasts;
  • A simple word similar to mono and koto;
