Commoratio
A figure in which the speaker lingers on the same point by restating it in different words — dwelling for emphasis.
Commoratio (Latin 'a lingering') is the figure of deliberate dwelling: instead of stating a point and moving on, the speaker restates it two, three, or four times in different words, refusing to let the audience get past it. The classical handbooks — the Rhetorica ad Herennium and Quintilian — describe it as the rhetor's way of ensuring that the strongest point in an argument does not slip by unnoticed.
The figure is more than repetition. It selects one idea as the axis of an argument and holds the audience there, turning the idea over so its faces are seen from several angles. In practice it usually combines with other figures — synonymia (piling up near-synonyms), distinctio (drawing fine differences), rhetorical questions — but the underlying move is a refusal to leave.
Modern audiences are impatient, and commoratio has to be handled with care. A paragraph that says the same thing four times feels padded rather than emphatic if the four ways do not each add something. The versions have to sharpen, deepen, or specify the point; commoratio done well feels like a camera moving in, not like a needle stuck.
Common mistake: confusing commoratio with tautology. Tautology restates the point in identical form and adds nothing; commoratio restates the point in a form that reframes it. The test is whether the second and third versions would be missed if they were cut. If they would not, the passage is padding; if they would, it is a figure.
“You come here now to plead with us. You beg us, you entreat us, you throw yourself upon our mercy — as if mercy were a thing that could be claimed by the man who denied it to every petitioner who came to his own door.”
