An anagram is a word formed by rearranging all the letters of another word, using each letter exactly once. These words use every letter from "HLAORENPI":
A mock sun appearing in the form of a bright light, sometimes near the sun, and tinged with colors like the rainbow, and sometimes opposite to the sun. The latter is usually called an anthelion. Often several mock suns appear at the same time. Cf. Paraselene.
