When I looked up these two terms, I found the following translations:

ので: as, because (of), since, owing to, on account of, by reason of, the reason is, given that, that being the case, etc.

のために: for the sake of, in favour, for the cause of, for the purpose of, due to, because, etc.

It seems that there is overlap between the two terms. So let me try to give an example:

I was despised for speaking English.



For this example, is there a difference between using ので and のために? If so, what is it?

Your second example 私は英語を話すために軽蔑された is ungrammatical, I'm afraid. のために should follow a noun or noun form.
×「Verb+のために」 ◎「Noun+のために」◎「Verb+ために」
... So 「話すために」 would be grammatical. (You use ために after a verb or adjective.)


These sentences are correct (as far as grammar goes... I might say it as 話したために/話したので or maybe 話すという理由で depending on the context) and mean pretty much the same thing. ために sounds more literary and more formal than ので. And ために can have a nuance of "just/only because".

Another example...


All these can be translated as "because", but ために can have a nuance of "only/just because", with more emphasis on the reason than on the result. ため, ために sound more formal and more literary than ので, and から sounds more casual than ので.

  • Interesting... but does this COMPLETELY invalidate my answer, or am I correct that there are cases where you cannot use ために and must use ので? Commented May 20, 2018 at 2:51

When you use the ので pattern, it is because you are describing the reason that something has happened/is going to happen. If you can say "because", and you can flip the order of the clauses and say "so", you use ので

"I had to go home again because I forgot my book."
"I forgot my book, so I had to go home again."

Zoos are not fun, because I'm scared of animals."
"I'm scared of animals, so zoos are not fun (for me)."

When you use the のために pattern, it's because you want to tell the purpose of an action or thing. Basically, if you can phrase what you want to say as a "for the purpose of" or "in order to" statement, you use のために or verbために to link the two related clauses.

"I need his phone number (in order) to ask him a question."

This phone is for (the purpose of) (use in) emergencies.

  • Eric, I think this is correct, but you might want to explain why the 理由 meaning of ために doesn’t apply here. Also remember that の is dropped after a verb.

    Hmm? 「ために」 has two meanings... can indicate 理由/reason ("because") as well as 目的/purpose ("in order to"), you know?

  • @Chocolate , you can translate 私は英語を話すために軽蔑された。 into "I was despised because I spoke English." ?? That sounds so wrong to me... 0_0 Commented May 20, 2018 at 2:37

    ^ いや「英語を話すために軽蔑~」のほうが「英語を話すので軽蔑~」よりいいとは思いませんけど。「~話すという理由で[見下]{みくだ}された」「~話すからといって見下された」とかのほうがわかりやすいと思いますし。
