What is the correct usage of IN and ON in a sentence.
NOT A TEACHER
(1) I believe that there is no "correct" usage.
(2) It is idiomatic. That is, it depends on what a group of people decide to use.
(3) Here are some examples that show how "crazy" the situation is:
(a) In California, we stand in line, but people in New York stand on line.
(b) In the United States, we live on Maple Street; in England, they live in
(c) Probably, today most Americans say in an elevator; probably most said
on an elevator back in the days when I was young.
(d) In the United States, on the street often means on the sidewalk; in
actually means in the middle of the street.
(e) In the United States, we ride on the subway but in a subway car (carriage). And
we say that there are police officers watching for suspicious activity in the subway
(f) You sit in an armchair; you sit on a sofa, bench, stool. If the chair does not
have arms, some people prefer on a chair while others prefer in.
(4) As you can see, the situation is "crazy." I suggest that you keep a notebook.
Write down examples of "in" and "on" that you see in the American and British
media. Then, little by little, you will start to get an idea of what is "correct."
