から and ので formation/conjugation differences


Consider the case when `から` and `ので` follows a noun, な-adjective, or noun-
equivalent:

> から：静か **だ** から... "Because it is quiet..." (Subjective causality)
>
> ので：静か **な** ので... "Because it is quiet..." (Objective causality)

**(Question)** What causes the difference in the parts in bold above?

* * *




`から` 'since, because' attaches to a clause, whereas `で` 'with (the reason
being)' attaches to a noun. `静かだ` is an indicative clause (ordinary sentence),
so you can simply attach `から`, but not `で`.

>   * 静かだから
>   * × 静かだで
>

In order to use `で`, you have to have a noun. To do that, you use the formal
noun (or nominalizer) `の` taking an appositive clause. In appositive clauses
and relative clauses, na-adjectives take the adnominal ending `～な`.

>   * × 静かなのから
>   * 静かなので
