The adjective broad boasts an extensive — you might even say broad — array of subtly different meanings including wide, spacious, far-reaching, vague, and unsubtle.
It's kind of funny that the word broad can communicate such an expansive range of ideas since expansive is, in fact, a synonym for broad. This adjective can be used to describe actual physical spaces. A broad highway, for example, would be difficult to cross because of all the cars in the many lanes of the road. The word can also be used more figuratively. American history covers a broad range of topics and events. A broad-minded person is open to new ideas, while broad humor aims for a mass audience with obvious gags and stunts.
