Question

1. The house is close to the river.
2. The house is near the river.
3. the house is by the river.
4. The house is next to the river.

Are they all the same and grammatical? Do we have some more similar expressions?

Answer 1

All are correct and all are used. We might also say, "The house is on the river", which is technically incorrect (grammatically correct, but the house is presumably not floating). It is commonly used, though.
