When do you use a capital letter for directional words like north, south, east, and west? Of course, when any word begins a sentence it should be capitalized, but you also capitalize directional words when you are naming a region. For example:
We live in the Midwest.
The West was once a wild frontier.
I'd love to visit the Northeast in the fall.
HINT: When you see a "the" before the directional word, it's probably a region name that needs to be capitalized!
If you are using it as a direction, it should not be capitalized. For example:
Turn west at the stop sign.
My house is southeast of the park.
Head north for three miles, then turn east at the light.
