What was the biggest lie that Americans ever told each other... according to Mr. Twain?.

AMERICA. But we are fearfully and wonderfully made, and we glorious Americans will occasionally astonish the God that created us when we get a fair start. We are called the nation of inventors.

See is the english verb.

Betray, destroy, and obey do not need to be changed to add the suffix -ed, because the "y" at the end of each word is preceded by a vowel  (so  they would be spelled  "betrayed," "destroyed," and "obeyed").

but hurry is different; it has to  be spelled "hurried" because the "y" at the end of "hurry" is preceded by a consonant.
