• “Brackets are also used to distinguish parenthetical information that appears within a larger set of parentheses. (Informally, though, it is quite common to simply use a second set of parentheses.)”
• “Brackets are also used to distinguish parenthetical information that appears within a larger set of parentheses. (Informally, though; it is quite common to simply use a second set of parentheses.)” I have read uses of semicolon in sentences, but i don't understand the meaning of second sentence. In fact, i did not notice that semicolon can be used after a simple word, as in when mentioning a synonym of a word next to it.

In informal settings, it's common to use another set of parentheses.

This is done informally. However, using another set of parentheses is common. This is not what the writer meant. As emsr2d2 said, the semicolon is an error.

The semicolon in the second sentence is an error whether or not the article says it is. It's grammatical, but it makes the sentence illogical.

Semicolons are commonly used in definitions as in your final example.
