「から」の情報

から can have several different meanings in Japanese, depending on which part of the sentence it is in, and what comes before/after it. It is often translated as 'because', or 'since'. In these cases, it just means 'Because of (A), (B)'.

から may be used with almost any type of word, but when the nuance is 'because', it will require だ before it when following a noun or な-Adjective.

Despite having several different nuances, it may be easier to think of から as meaning 'from' in all situations, as that is the base nuance.

From (A as a reason), (B) = Because/Since.

From (A as a location), (B) = From.

Fun Fact

から is a special type of particle in Japanese called a case marking particle. These are particles that describe the relationship that (A) and (B) exist in. We will learn more about these soon!

Hey @MikkaT !

The だ used here and in けど is this. The reason that だ needs to be added after nouns and adjectives are the same reason you need to add ‘is’ in English.

For example, 大きい会社だから、人がたくさんいる (natural) VS 大きい会社から人がたくさんいる (unnatural) is the same as comparing ‘Because it is a big company, there are a lot of workers’ VS ‘Because big company, there are a lot of workers’.

Although they may look the same, だから, in the vocabulary section is a conjunction (接続詞), and だ+から is a case marking particle (格助詞). This means that だから is used to connect the first sentence and the second sentence like in the image you have attached. This is kind of similar to how grammar points like しかし is used!

I hope that answers your question!

Hi, yes that makes it a bit clearer. Thank you.

What is the difference between the following quiz answers?
- 私は犬が好きですから
- 私は犬が好きだからです
- 私は犬が好きだから
I assume だから is less polite than the others, but then what’s the difference between ですから and だからです? Are they basically equivalent? Are there situations where I should prefer one over the other?
