The En Dash: Ranges and Connections
Use an en dash to connect inclusive ranges of numbers, dates, or times, and to join a prefix to a proper open compound.
The en dash signifies a relationship, often read as 'to' or 'through'....

Challenging
Analyze this sentence from a work of critical theory: 'This phenomenon—what Foucault might call a 'discursive formation'—is not a naturally occurring event but a product of power relations operating across the 18th–19th centuries.' What is the most precise justification for the author's choice of em dashes over parentheses?
A.The em dashes are used because the sentence is long and complex.
B.The em dashes signal that the enclosed information is a direct quote.
C.The em dashes elevate the parenthetical, positioning the theoretical term not as a mere aside, but as a central, emphatic lens for the main clause.
D.The em dashes are a less formal choice, making the complex theory more accessible to a general audience.
Challenging
Why do rigorous academic style guides like MLA and Chicago insist on a typographically distinct en dash (–) for ranges and connections instead of simply allowing the more common hyphen (-)?
A.To make the text look more aesthetically pleasing and varied.
B.To reserve the hyphen exclusively for separating syllables at the end of a line.
C.To create an unambiguous visual distinction between the function of joining (hyphen) and the function of indicating a range or relationship (en dash), enhancing clarity and precision.
D.To align with British English conventions, which have historically favored more complex punctuation.
