Completing

Completing is the act of bringing something to an end, finishing a task, or achieving a final, whole state. It can describe a process, a project, a piece of work, or a transition from unfinished to finalized status.

The word derives from Latin completus, via French compléter, and is used as a verb, a present participle (completing), and a noun (completion).

In everyday and professional contexts, completion is tied to meeting defined criteria or delivering usable results. Project management often uses a definition of done or acceptance criteria to mark when a task or project is complete.

In mathematics, completing appears in the phrase completing the square, a technique used to rewrite a quadratic expression in a form that exposes its vertex and simplifies solving equations.

In law and business, completion commonly refers to the closing of a transaction, such as the transfer of ownership in real estate or the finalization of a corporate acquisition, which occurs when contractual conditions are satisfied.

In computing and games, completion can refer to processes finishing, tasks reaching 100 percent, or players finishing all available content, though definitions vary by context.

The term is closely related to completeness and the state of being complete, which emphasize wholeness rather than mere partial progress.
