Section 17.4 Information Structure
Consider two sentences reporting the same fact: The proposal was controversial followed by Lengthy debates resulted from this controversy—versus the same pair written as The proposal was controversial. This controversy led to lengthy debates. The second version flows more smoothly, and understanding why reveals something fundamental about how readers process prose. Sentences do not exist in isolation; they are part of a discourse, and the reader is always working to connect each new sentence to what came before. The way you arrange information within a sentence—what you put first, what you save for last—determines how easily the reader makes those connections.
How you arrange information within a sentence affects clarity and emphasis.
Given vs. New Information.
Given information: What the reader already knows.
New information: What you are adding.
Effective prose moves from given to new:
-
The proposal was controversial. This controversy led to lengthy debates.
The second sentence starts with the given information (This controversy) and ends with the new (lengthy debates).
End-Focus.
English naturally emphasizes information at the end of sentences. This principle is called end-focus:
-
The winner was Maria. (emphasizes Maria)
-
Maria was the winner. (emphasizes being the winner)
Place your most important information at the end.
End-Weight.
English prefers heavy (long, complex) elements at the end of a sentence. This principle is called end-weight:
-
Awkward: That she would resign surprised everyone.
-
Better: It surprised everyone that she would resign.
This is why extraposition exists—to move heavy subjects to the end.
