* Generally, only one exclamation mark is used at the end of a sentence to indicate strong emotion, surprise, or emphasis.
* Using two exclamation marks is considered unconventional and can be seen as excessive or even humorous.
However, in some informal contexts or online communication, two exclamation marks might be used for extra emphasis or to convey excitement.
Here are some examples:
* Correct: "What a beautiful day!"
* Incorrect: "What a beautiful day!!"
* Informal: "I'm so excited to see you!! 😄"
It's always best to stick to one exclamation mark unless you're deliberately aiming for a specific effect in informal settings.
