awesome

The story

From awe + -some; compare earlier awful and Middle English eiful (“inducing fright or terror, terrible”), from Old English eġeful (“fearful; inspiring awe”). The oldest meaning of awesome is of “something which inspires awe”, but the word is now also a common colloquial expression. It was originally so used in the United States, where it had featured strikingly in the 1970 film Tora! Tora! Tora!, as used by Japan's Admiral Isoroku Yamamoto to describe the "awesome" industrial potential of the United States. Consequently, as the word popularly became an expression for anything superb, in its original meaning it has tended to be replaced by the related word, awe-inspiring.

First known use, by meaning

• from 1590–1600. Causing awe or terror; inspiring wonder or excitement.
