Yes, ‘street’ is a common noun. Common nouns are general names for a person, place, thing, or idea rather than the specific name of a particular one. In this case, ‘street’ refers to any street in general, without specifying which one. For example, when we say ‘I walked down the street’, we are not referring to a specific street but rather to streets in a general sense.
On the other hand, if we were to say ‘Main Street’, we would be using a proper noun since it is the specific name of a particular street. Proper nouns always begin with a capital letter, while common nouns do not. Therefore, ‘street’ is considered a common noun.
