Definition: The exclamation - ! - is a punctuation mark used in English and other languages to denote an exclamatory statement such as extreme happiness, shouting, or surprise. Also used in some math and computer programming languages. The mark used as an exclamation was originally a way of writing IO, a Latin word meaning exclamation or expression of joy.
Two theories as to the form of the exclamation are:
1) Scribes saved space by putting the I above the O with the O eventually becoming a filled-in dot;
2) It was originally written as an O with a slash through it but the O eventually disappeared and the remaining slash evolved into today's exclamation mark.
