Time to get a little closer with contiguous, a word likely most familiar in the phrase "contiguous United States." Otherwise known as the conterminous United States, this region comprises the collective states within the U.S. that connect geographically by shared borders, as well as the nation's capital. Looking for a word to describe freestanding states like Hawaii and Alaska, or seabound territories along the lines of Guam and American Samoa? Today’s word has a direct antonym: noncontiguous. Both come from the Latin verb contingere, meaning "to be in contact with."
