Donald Trump said "I walk in the street" at 0.51 Source
Shouldn't it be "I walk on the street"? Is this an error?
Maybe this will help:
...walk on the street..
Would be interpreted by a native speaker as literally on top of the the surface of the street.
The in in Trump's quote is a colloquialism particularly used with walking :
...walk in the street...
referring to the street and its environment. What Trump is saying is that he has seen and experienced what the average person sees and experiences. That he is in touch with the public since given his status and wealth, one might not expect him to do this. He might have said:
I walk the streets
but this would have a slightly different meaning.
This should not be confused with:
They found her doll in the street.
which means the doll was found within the boundaries of the street.
