In beginning Spanish language classes, they teach you how to say the four points of the compass: norte, sur, este, oeste.

But they usually fail to teach you the adjectives that go with these nouns:

norte: septentrional (northern)

sur: meridional (southern)

este: oriental (eastern)

oeste: occidental (western)

And note that oriental can also be a synonym of uruguayo and thus mean "Uruguayan" because the official name of Uruguay is la República Oriental del Uruguay (meaning the republic east of the Uruguay river).
