Dirimens Copulatio

Dirimens copulatio is the figure of adding a balancing consideration to a claim so that the statement is not left one-sided. The Latin means roughly 'a joining that interrupts', and in practice it takes forms like 'not only X but also Y' or 'yes, X — but consider Y as well'.

The purpose is credibility. A speaker who volunteers the qualification appears to have already weighed the objection, which makes the original claim harder to attack. It is the constructive cousin of procatalepsis: where procatalepsis raises an objection in order to refute it, dirimens copulatio raises a complementary truth in order to keep it.

It is a workhorse of persuasive prose precisely because it is invisible. Most well-argued paragraphs contain one — a clause that concedes scope, adds a second cause, or notes that the easy explanation is only part of the story — and readers register it as fairness rather than as technique.

Common mistake: using it to hedge everything. A paragraph in which every claim is immediately balanced reads as a writer with no position; the figure works because it is the exception in a sentence that otherwise commits.
