Using から (because) with nouns, adjectives and verbs


Could someone please check my understanding of how から is used with nouns etc?

Today I read what I think were some rules. から needs だ/です depending on what
precedes it.

> しずか ですから 散歩しましょう

-na adj, needs です.

> 天気がいいから 散歩しましょう

-i adj, doesn't need です

> コーヒーを飲むことですから、しずかにしてくれ

noun, needs です.

> 猫がいますから、しずかに してくれ

verb, doesn't need です




I think you have the right idea- nouns and na-adjectives require a copula
(だ・です) before it. That way, it doesn't get mixed up between the "from" meaning
of から.

> しずか ですから 散歩しましょう

Correct; a copula is required if a na-adjective comes before から.

But I do want to point out that you _can_ still use だから (as opposed to ですから)
even if the sentence is polite. The most important thing is that the main
(i.e. final) verb is in the polite form.

> 天気がいいから 散歩しましょう

Correct; with い adjectives using だから is ungrammatical. (You actually _can_ use
ですから with an い adjective, but it isn't necessary.)

> コーヒーを飲むことですから、しずかにしてくれ

You are correct that you'll need だから or ですから after the noun こと. But I don't
see any reason to have こと there at all. It should just be 飲むから (or, in this
case, 飲んでいるから).

Also, the inconsistency in politeness here is a little strange. You used
impolite -てくれ at the end, but polite ですから in the middle. It is weird to have
an impolite independent clause with a polite dependent clause. But that's not
what this question is about.

> 猫がいますから、しずかに してくれ

Correct; だ or です do not (and cannot) immediately precede から if there is a verb
and not a noun or na-adjective there. (However, this sentence also has the
same problem as last time with the inconsistent politeness)
