This question is an exact duplicate of:
Ok, I found this sentence "The real entrance is actually around the back of the house, on the ground floor" in this article
This building has 4 sides
-The orange one is the front of the building
-The green one is the back of the building
-The purple one is one side of the building. The other side of the building is not colored.
So, What does it mean when we say "the main entrance is around the back of the building"?
Does it mean the main entrance is at the green or purple one?
Note: The orange side faces the main street
Also, in the dictionary
Around (preposition) d : on or to another side of (something)
We were surprised by what we saw when we walked around the corner.
There's another door around the back of the house.
if this meaning applies to the word "around", it means the main entrance is not at the back of the house but on one of the sides of the house
