Over the course of American history, American English has diverged from that spoken in England. A number of words and word uses therefore developed that were uniquely American in origin. Although many of these words were once dismissed as "barbaric" by those who favored British English, they have sense entered common usage worldwide—testimony to the enduring strength of American English.

aboveboard (as a term indicating dealings free of deceit or duplicity)
accountability
ahead
appreciate (in the sense meaning "to increase in value")
awful (in the sense meaning "very bad")
