Definition and meanings of “okaasan”

Let me start with the definition and meanings of okaasan.

• okaasan – お母さん (おかあさん) : a noun meaning a ‘mom’ or ‘mother’ in Japanese. This can also work as plural. Learn more about Japanese plural.

Normally, this noun is used by a child to call his/her mother. So, the usage is very similar to that of mom in English, I think.

The definition and meanings are simple and clear. To understand this noun more clearly, however, let me explain its kanji-mixed expression in detail.

Okaasan in kanji

The kanji-mixed expression of okaasan consists of the following three components:

• o – お : a prefix making its following word polite.
• kaa – 母 (かあ) : a noun which can mean a ‘mother’ in Japanese.
• san – さん : an honorific suffix often used after a name to make it sound polite.

From these three components, we can understand that okaasan is literally the polite expression for a mother in Japanese. And actually, it is. In Japan, children call their mothers with showing their respect. It’s also worth mentioning here that this noun is not suitable for formal situations. Japanese people often try to be polite by lowering their positions. In formal situations, therefore, they often call their mothers in a less polite way: they do not want to respect their mothers more than the listeners in conversations.

When we meet new Japanese words, we should check their grammatical components in detail to understand their meanings clearly and deeply. In many cases, grammatical components tell us a lot about the meanings of the words they form. Actually, here, we could get the better understanding of okaasan through the detailed check above.

So far, I’ve explained the definition and meanings of okaasan together with its grammatical components. Then, let me explain how to use it through the example sentences below.
