TermCentral meaning
Expected formWhat preceding wording and normal construction lead one to anticipate
Demands of the situationThe form best suited to the addressee and communicative purpose
Departure from expectationUsing another grammatically valid form for a rhetorical benefit
After a person has been named, a pronoun would ordinarily suffice. Repeating the name can nevertheless honor, warn, alarm or recall an attribute. It should not automatically be labeled purposeless repetition.
Not every unexpected form is rhetorically successful. A discernible benefit and contextual basis are essential.
