noun

mirage

muh-RAHZH/məˈrɑːʒ/

An appearance created by bent light that misrepresents what is there.

The mirage makes a distant palm appear reflected in water above dry sand.

Desert optical mirage: small isolated stretch of hot pale sand, lone distant palm appears inverted in shimmering apparent water that dissolves into dry foreground; visible heat wavering, sparse white surround.
Etymology

French mirage named the deceptive appearance of objects reflected in desert water. It may derive from se mirer, “to be reflected,” though the source also offers Latin mirus, “wonderful,” as an alternative.
