reappear

Reappear is a verb meaning to appear again after having disappeared or ceased to be visible, present, or evident. The term describes a return to a previous state of visibility or occurrence, occurring after an interruption or absence. The word is formed from the prefix re- meaning again and the verb appear, and it concentrates on the action of coming into view once more.

In usage, reappear is common in everyday speech as well as in specialized contexts. For example, someone might say a missing item reappeared after a search, or a weather pattern reappears after a calm period. The third-person singular form is reappears, the present participle reappearing, and the simple past tense reappeared. The related noun reappearance refers to the act or instance of coming back into view.

In scientific and medical contexts, reappear is used to describe phenomena that return after an interruption. In astronomy, a celestial object such as a star or comet may reappear in the sky after being obscured or out of view. In medicine, symptoms may reappear after a period of remission, and clinicians may document a reappearance of signs to inform treatment decisions.
