West
In short
West is one of the four cardinal directions on a compass. It is the direction exactly opposite to east where the sun appears to set.
In plain words
If you face north, west is to your left. It is a way to describe where something is located or which way you are travelling.
A simple example
If you are driving towards the sunset in the evening, you are travelling west.
Why it matters
It is essential for navigation, map reading, and understanding global geography. Without cardinal directions, it would be difficult to give precise locations.
Easy to mix up
It is often confused with northwest or southwest, which are intermediate directions between north and west.
