Completed

Completed is the past participle of the verb complete and an adjective describing something that has been finished or brought to an end. It signals that all required steps have been completed or that a state of readiness has been achieved. In usage, it often appears in sentences such as “The task is completed” or “The form is completed.” As an adjective, completed emphasizes finality rather than ongoing effort and contrasts with incomplete or in progress.

Etymology and forms: completed derives from the Old French complet, from Latin completus, the past participle of complere (to fill up, to finish). The form entered English through medieval French and developed into modern English usage as both a participle and an adjective.

Grammar and usage notes: completed commonly occurs with auxiliary verbs in perfect tenses, as in “has completed,” “had completed.” It also serves as a postpositive adjective in phrases like “the task completed by the team.” In many contexts, complete remains more general (as an adjective or a verb), while completed denotes that the process of finishing has been realized.

Specialized senses: in mathematics, completion is a standard concept; a completed object often means it has undergone a process to attain a property such as completeness (for example, a completed metric space, or a completed ring with respect to a topology). In software and project management, “Completed” is a status flag indicating that a task, workflow, or transaction has ended and is closed.
