Learn English – :What is the difference between “Road”, “Avenue”, “Street”

"A road is a thoroughfare, route, or way on land between two places, which has been paved or otherwise improved to allow travel by some conveyance, including a horse, cart, or motor vehicle."

"A street is a paved public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about."

"In landscaping, an avenue or allée is traditionally a straight route with a line of trees or large shrubs running along each side, which is used, as its French source venir ("to come") indicates, to emphasize the "coming to," or arrival at a landscape or architectural feature. In most cases, the trees planted in an avenue will be all of the same species or cultivar, so as to give uniform appearance along the full length of the avenue."

These descriptions came from https://en.wikipedia.org by searching for "road", "street", and "avenue" - I would have posted direct links to each of these, but need more rep in order to post more than 2 links in an answer. I just found this site today.

So from these descriptions - a road is an improved path between two points whether in areas outside settlements, in the suburbs, or in urban areas, while a street is a paved public path within a built up area, and an avenue is a road or street with trees planted along both sides, generally of the same species for uniformity.
