Punctuation Marks

Punctuation marks are symbols are vital to disambiguate the meaning of sentences.

For example:

1) "woman, without her man, is nothing"

2) "woman: without her, man is nothing"

Both sentences have greatly different meanings.

The rules of punctuation vary with language, location, register and time and are constantly evolving. Certain aspects of punctuation are stylistic and are thus the author's (or editor's) choice. Tachygraphic language forms, such as those used in online chat and text messages, may have wildly different rules.

Below you'll find the most commonly used in both English and Portuguese languages.
