 sense of wonderment. One theory of its origin is that it was originally a Latin exclamation of “joy” (io), written with the “I” above the “o”.

The exclamation mark was introduced into English printing in the 15th century, and was called the “sign of admiration or exclamation” or the “note of admiration” until the mid-17th century. In German orthography, the sign made its first appearance in the Luther Bible

 (“Stop!”), or intended to be astonishing or show astonishment: “They were the footprints of a gigantic hound!” Exclamation points can also be placed mid-sentence with a function similar to a comma: “On the walk, oh! there was a frightful noise.”

Casually, exclamation marks may be repeated for additional emphasis ("That's great!!!"), but this practice is generally considered unacceptable in formal prose.

The exclamation mark is sometimes used in conjunction with the question mark

Overly frequent use of the exclamation mark is generally considered poor writing, for it distracts the reader and reduces the mark's meaning.
