I am having some real difficulty distinguishing から and ので and I could use some help. Bunpro says から emphasizes causes and ので emphasizes effects, but honestly I have no idea what that means. In the sentence “because it is Saturday, I want to go on a trip,” the cause is Saturday (the first part of the sentence) and the effect is going on a trip. “Because it is Saturday” is first, and that’s where the Bunpro blank is, so so I would assume から, right? Because it emphasizes causes. WRONG. It’s ので.
To make this even more complicated, every other source I consult about this says something different. This site says:
The conjunctions kara （から） and node （ので）both express reason or cause. While kara is used for reason or cause of a speaker’s volition, opinion and so on, node is for existing (existed) action or situation.
So this seems like から is about opinions and ので is about existing actions. This makes sense on the face of it. “Because it is cold, I stayed home”? ので , because it’s about staying home, an action. “This car is old, so I want a new car”? から, because wanting a new car is an opinion.
However, when you look at that Bunpro sentence from earlier (“because it is Saturday, I want to go on a trip,”), this logic falls apart. Wanting to go on a trip seems like an opinion, and not an action (since it isn’t actually happening), so から is the obvious choice. But it’s ので! I just don’t get it.
If someone could please explain this to me, I would be eternally grateful!
