[Middle English aperen, from Old French aparoir, aper-, from Latin appārēre : ad-, ad- + pārēre, to show.]

Synonyms: appear, emerge, issue, loom1, materialize, show
These verbs mean to come into view. Appear and show are the most general: A ship appeared on the horizon. Her shirtsleeve shows at the edge of her jacket.
Emerge indicates appearing after having been obscured from view by something: "Baby sea turtles emerged from the sand to scramble to the sea" (Julia Whitty).
Issue emphasizes the point of origin of whatever is appearing: "Here and there smoke issued from chimneys" (Jeffrey Tayler).
To loom is to come into view as a massive, distorted, or indistinct image, and often that which looms is considered threatening in some way: As the hikers near the mountain's summit, storm clouds loom over the horizon.
Materialize means to appear suddenly and sometimes mysteriously, as if out of nowhere: "The field ... had been empty the day before when he walked around the city. The circus has simply materialized" (Erin Morgenstern).
