When telling people your location there are two ways you can do it.
You can give them the relative location, or the absolute location.
Using the word relative gives you a clue to how this works
Relative – related – a relationship
So using this requires a relationship between two places.
Telling someone where I am with a relative position means I’m telling them where I am related to another location.
For example — I’m across the street from the school.
Or — my school is NORTH of the school. So, the school is South of my house.
But you don’t have to use directions necessarily. You can use distance too.
My House is 1 mile away from the school.
Or even time —
My house is 5 minutes away from the school.
You could use cost as well.
My house is a $1 taxi ride away from the school.
And of course you could combine them in various ways.
My house is a 5 minute drive heading north one mile from the school.
So, the main take away from the relative location is that it is not a fixed location. It changes based on your current location.
If I’m at my house the store is south of me, but if I’m at school the store is North of me. Someone in the city next to use might be over here and would say that the store is west of their house. Or, in a city on the other side might say that the store is west of them.
Relative location is used regularly in common conversations. People rarely will give you precise locations when describing how to get to common locations.
But sometimes, a relative location is not very useful. In those moments we will use an Absolute Location.
