- Which one is correct?
- I go to school by foot.
- I go to school on foot.
- Are there instances when the expression by foot is preferred?
My last question is the following:
- Why is the singular noun, foot, used?
If a person goes to school by bus/train/car they are using only one means of transport, they are travelling in one car not two. But people use both feet for walking, so why would the following expressions be ungrammatical?
- I go to school by feet
- I go to school on feet
I read the answers on this question why is it always "on foot" not "on feet"? but they did not convince me.
