Parentheses ()

Parentheses are the bracket () [] <> {} . The singular form is parenthesis. We only use parentheses in a few specific usages.

Separate Optional Information from Main Sentence(s)

These information are optional. Without them, it does not deviate the context from the main sentence. Example

The cookie (which was still warm) was delicious.
The cookie was delicious.

Show Interruption

Adding emotion or additional clauses to modify the main context deliverable means.

Paige says, "Furthermore (*coughing*), I must firmly state that nuts are not necessarily round".

Specify a Definition or Referencing

Denote a reference or origin.

Eisenstein said, "time is relative." (Sept 12th Entry, Personal Diary, page 34)
