Which formatting should not be done when quoting four or more lines from a character's speech in an essay?

When quoting four or more lines from a character's speech in an essay, using a block quote format is the standard practice. This involves starting the quote on a new line and indenting it from the left margin, which visually distinguishes it from the rest of the text. Including the author's name is also essential for providing proper attribution and context for the quote, which is crucial in academic writing to respect intellectual property and contribute to the credibility of your argument.

Italicizing the lines is not a typical requirement for block quotes; rather, the focus is on maintaining clarity and formatting consistency. Therefore, underlining the lines is unnecessary and not standard practice in academic essays. It does not serve any functional purpose in relation to block quotes and can distract from the content being presented.
