Why do women call themselves "daughter-in-law" after marriage?

In fact, in ancient times, I wrote "Xi's wife fu". Next to it is a female word added by modern people for convenience of expression. Become a proper noun for a son's wife.

The word fu, as we all know, refers to women. In Oracle Bone Inscriptions, the word "Fu" is written like this.

A woman was kneeling with something like a feather duster.

What are you doing?

Clean it up

Why are you cleaning?

Because she is the hostess of the family.

Therefore, the meaning of a woman originally refers to the mistress of the family, that is, a married woman.

In Han Yuefu's Peacock Flying Southeast, there is a poem similar to "Seventeen years old is a gentleman's wife".

Therefore, if we only refer to married women, the word "woman" is enough.

So what does "daughter-in-law" mean?

As mentioned earlier, the word "daughter-in-law" was originally a word "Xi", and was later added by later generations to refer to the wife of his son, which became a special word.

But what does son have to do with the word "interest"?

It still depends on how the original information word is written.

Below is a heart word with a self on it, which is actually the shape of the nose.

So rest is breathing with the heart as the nose. That is, the fetus has no nose and mouth, and only breathes with the help of the mother's heartbeat.

Since this is the original intention, the word "interest" gradually derived the meaning of reproduction, and the word "childlike interest" came into being.

Therefore, the son's daughter-in-law is called "woman" for short. Later, it gradually evolved into a "daughter-in-law" and became a proper term for married women.

However, knowing the evolution of the word "daughter-in-law", will there be psychological shadow when calling a daughter-in-law next time ~ ~ ~
