Cut out all these exclamation points...An exclamation point is like laughing at your own joke.
Stop!
A sentence ending in an exclamation mark may represent an exclamation or an interjection (such as "Wow!", "Boo!"), or an imperative ("Stop!"), or may indicate astonishment or surprise: "They were the footprints of a gigantic hound!" Exclamation marks are occasionally placed mid-sentence with a function similar to a comma, for dramatic effect, although this usage is obsolete: "On the walk, oh! there was a frightful noise."[12]
That's great!!!
Informally, exclamation marks may be repeated for additional emphasis ("That's great!!!"), but this practice is generally considered unacceptable in formal prose.[13]
?!
The exclamation mark is sometimes used in conjunction with the question mark. This can be in protest or astonishment ("Out of all places, the squatter-camp?!"); a few writers replace this with a single, nonstandard punctuation mark, the interrobang, which is the combination of a question mark and an exclamation mark.[14]
Overly frequent use of the exclamation mark is generally considered poor writing, for it distracts the reader and devalues the mark's significance.[15][16]
