からbecause; so
から is "because". The reason comes first and what follows from it comes after, so in English "so" is often the closer fit.
We still have time, so let's take a short break.
It is dangerous, so please be careful.
It's Sunday today, so the bank is closed.
How to form it
Plain or polite sentence + から
寒いから, 行くから, 寒いですから, 行きますから. A noun or a な-adjective needs だ or です first: 休みだから, 静かですから. The reason can stay plain even when the sentence ends politely.
The reason comes first
English "because" goes in front of its reason. から goes at the end of it. What follows can be anything: a fact, a wish, a suggestion, a request.
I did not eat breakfast, so I got hungry.
This book is interesting, so I want to read it again.
It is cold outside, so please wear a coat.
After a noun: だから
Without だ, から straight after a noun is a different word: "from".
It's nine o'clock, so let's begin.
With だ: because it is nine.
Let's begin at nine.
Straight after the noun: from nine.
Not said: 今日は
(Today is my day off, so I'm staying home.)
It is 休みだから.
Giving only the reason
Asked why, people give only the reason and stop at から, or at からです in polite speech.
Why didn't you come yesterday?
Because I had a fever.
You can also say something first and add the reason afterward, as a sentence of its own.
I'm not going today. Because I have no money.
Please wait here a moment. I'll be right back.
English has nothing for this から. It makes your promise the reason they can wait.
から or ので?
Both mean "because", and in most sentences either one is right. ので is the softer one.
I have a headache, so I am leaving early today.
Your reason, stated outright. To a boss it can sound blunt, as if you were arguing your case.
I have a headache, so I am leaving early today.
The same reason, given as the situation you are in.
