Afterthought

An afterthought is something added later to a plan, discussion, or object that was not part of the original version. It can be a remark, feature, or correction introduced after initial consideration or action. In everyday use, an afterthought is often a belated addition that may seem less central or essential, and it can carry a note of hesitancy or reconsideration.

In language, an afterthought emphasizes the sequence of thinking: it is thought of only after the fact. The term is a straightforward compound of "after" and "thought" in English, with no special figurative origin beyond the literal sense.

Examples include a late remark in a meeting such as, "And an afterthought—the project budget should be revised," or a product release that includes an afterthought feature added after feedback. In writing, an afterthought may take the form of a late clarification or disclaimer appended to an earlier statement.
