Earlier parts of the chapter considered omission, mention, single-word and clausal predicates, and definite and indefinite forms. Placement completes these choices: the same content can be rhetorically reshaped by changing its position.
Omission may achieve economy, definiteness can identify a familiar referent, a clause can strengthen attribution, and fronting can suggest restriction or anticipation. Labeling every result simply “emphasis” erases the distinctions established by the text.
