1. My father drives me to school.

2. I go to school in my father's car.
3. I go to school by my father's car.
[Can we use 'by' in the sentence?]

4. I go to school by car.
5. I drive a car to school.
6. I drive my car to school.
[Does #4 mean #5 or #6? When Father drives me to school, can we use #4?]

1 and 2 are fine.

3 isn't. To use "by" you'd be saying or writing something like these:
I go to school by car.
... by bicycle.
... by bike.
... by motor scooter.
... by bus.

etc.

4, 5, and 6 are all fine and basically mean the same thing.

And yes, if Father drives you to school, you can use #4.

My parents drive me to school by car.

Or
My parents drive me to school in car.
[Help me, thanks]

No, you can't use #4 if your father drives you to school

Car

Oh, the joy of dissecting sentences! Let's dive in and have some fun, shall we?

First, let's address the "by" question. In sentence 3, using "by" doesn't quite fit. "By" is more commonly used when referring to transportation methods like "by bus" or "by train." So, in this case, it's better to stick with "in" as in sentence 2.

Now, onto the difference between sentences 4, 5, and 6. Sentence 4 means just what it says: you go to school using any car, not necessarily your own. It's a general statement about your mode of transportation. Sentence 5 specifies that you are the one driving a car to school, regardless of whose car it is. Finally, sentence 6 suggests that you have your own car, and you're the proud driver who zooms off to school.

So, when your father drives you to school, we can say that sentence 4 fits the situation. It conveys the idea that you're going by car without specifying who the driver is.

I hope that clears up any confusion and brings a smile to your face!

Regarding your first question, the sentence "I go to school by my father's car" is grammatically incorrect. The correct sentence construction would be either "I go to school in my father's car" or "My father drives me to school."

Now, let's address your second question. Sentence #4, "I go to school by car," is a generic statement indicating that you use a car as a means of transportation to get to school. It does not specify who drives the car, so it could mean either #5, "I drive a car to school," or #6, "I drive my car to school."

In the context where your father drives you to school, it would be more accurate to use sentence #5, "I drive a car to school." This suggests that you are the one driving the car, indicating that you drive your own car to school. However, if you want to highlight the fact that your father drives you to school, you should use the sentence "My father drives me to school" as mentioned earlier.

To summarize:

- If you want to emphasize that your father drives you to school, use "My father drives me to school."
- If you want to specify that you drive your own car to school, use "I drive my car to school."
- If you want to express that you use a car as a mode of transportation without specifying who drives it, use "I go to school by car."
