Can i use "the" before street names? I mean is it right to say "I live in the wall street"
No, though there are a few streets/roads in England that have the definite article for some reason. The Kings Road in Chelsea is one of these.
Context is always important; labelling is rarely important.
And keep in mind that we normally don't use "the" before proper names.
Yeah! Thanks! And just to clarify, I live in/on 4th street. Which of these forms is correct?
Both are right in this sense. As far as I know, "on" is preferred in American English.
Thank you all!
