completed
"Completed" is the past tense and past participle of the verb "complete." It has a couple of closely related but distinct uses — as a verb describing a finished action, and as an adjective describing a finished state. It's a very common, everyday word you'll encounter constantly.
In official or administrative situations, 'completed' often means you filled in all the required fields on a form, application, or questionnaire — leaving nothing blank.
