2, 3. Onto.
Student or Learner
I have a question about the correct preposition to use. Suppose context is a driving car:
1. The car went into/onto a curve.
2. The car went into/onto a path.
3. The car went into/onto a road.
Should it be "into" or "onto"?
How is a curve different from a path or road, that "into" could be used with "curve" but not "path" or "road"?
I don't find any of them very natural.
If you are talking about driving, it is natural to talk about going into a curve and coming out of a curve. Like, "make sure to downshift going into a curve."
It's not really the same thing as being on a curve. It's about entering the curved section of the road.
I wouldn't say "onto a curve."
