Two funny pictures to show that punctuation matters. A lot. 🙂
Can you see the difference in meaning, if punctuation marks had been used?
English has 14 punctuation marks. American and Bristish English follow the same rules of punctuation but the names may vary. Here you are the main differences (source: grammar. yourdictionary.com): If you want more information about punctuation marks and their rules, click HERE.
Some other common symbols and their names are:
. dot (for webpages, for example)
# hash (also octothorp and in Am. English pound sign)
_ underscore (for email addresses, for example)
