“Because” in Japanese / Takai Node Kaenai / たかいのでかえない

Hi, this is Yuyujin.

We sometimes need to show reason.
This time lesson is “Because” in Japanese.
Let’s get started.

The basic pattern of “Because” in Japanese is
ANode B  (AのでB)
A Kara B  (AからB)
This sentence means “B because A.”
Here A is reason and B is a main sentence.

A Node B  (AのでB)
A Kara B  (AからB)

“Node(ので)” and “Kara(から)” is same.

Samui Node Watashi Wa Koto Wo Kiru
(さむいのでわたしはコートをきる。)
Samui Kara Watashi Wa Koto Wo Kiru
(さむいからわたしはコートをきる。)
I wear a coat because it is cold.

Kore Wa Takai Node Watashi Wa Kaemasen
(これはたかいのでわたしはかえない。)
Kore Wa Takai Kara Watashi Wa Kemasen
(これはたかいのでわたしはかえない。)
I can’t buy this because it is expensive.

Here “Takai(たかい)” means expensive.
Another “Takai(たかい)” meaning is “high” or “tall”.

Kaze Ga Tsuyoi Node Soto Wa Samui
(かぜがつよいのでそとはさむい。)
Kaze Ga Tsuyoi Kara Soto Wa Samui
(かぜがつよいからそとはさむい)
The outdoor is cold because wind is strong.

Kono Gemu Wa Omoshiroi Node Yamerarenai
(このゲームはおもしろいのでやめられない。)
Kono Gemu Wa Omoshiroi Kara Yamerarenai
(このゲームはおもしろいからやめられない。)
I can’t stop this video game because it is interesting.

When you want to ask the reason, you can say
A Nowa Naze Desu Ka
(Aのはなぜですか。)
Why A?

The answer is
B Kara Desu
(Bからです。)
Because B.

A Nowa Naze Desu Ka (Aのはなぜですか。)
