Japanese

We've already learnt から to mean because or since. We're now going to learn another way of giving reasons with ので.

ので and から are very similar, but ので sounds slightly more formal.

The reason always goes before ので, and the only difference between this and から is how nouns and な-adjectives are used with it:

ので	から
元げん気きなので	元げん気きだから
犬いぬなので	犬いぬだから
