Other forms: reappeared, reappears, reappearing
To reappear is to come into sight again. Gone for a while, and now back.
The word assumes an absence, which is why it is so useful in narrative: a character reappears, the sun reappears from behind a cloud, an old problem reappears. It works for people and for symptoms equally, and a doctor will ask whether a rash has reappeared. The noun is reappearance, which usually comes with a preposition and a time. The plain opposite is disappear, and both are built on appear.
1verbreappearTo become visible or present again.
“He reappeared an hour later with the tools.”

Built from
From re- + appear. appear comes from Middle English apperen, aperen, borrowed from Old French aparoir (French apparoir), from Latin appāreō (“to appear”), from ad (“to”) + pāreō (“to come forth, to become visible”), ultimately from Proto-Indo-European peh₂s- (“watch, see”), s-present of peh₂- (“protect”).
