I am aware that the word "above" has lots of meanings, such as
in or to a higher position than something else;
more than an amount or level;
in a more important or advanced position than someone else.
This post focuses on the first meaning, that is, "a higher position".
The following sentence is meaningful
It's on the shelf just above your head
since it tells me where is the thing I am looking for.
Technically, the sentence is correct "the bird is above the tree", although the bird is a bit far from the tree.
In real life, are there some situations where I need to use "above" to describe something far away?
