What does halo mean?
A halo is most immediately a ring of light surrounding a head, an object, or a celestial body. In religious and artistic imagery, halos signify holiness, radiance, or spiritual authority; in ordinary conversation, the word can describe the conspicuous admiration or prestige attached to a person or achievement. A halo also has a precise meteorological sense: a luminous circle around the sun or moon created by the passage of light through ice crystals in high clouds. The word therefore moves easily between visible light and figurative reputation, linking physical radiance with social or symbolic distinction. Its verb form, meaning to form or wear a halo, is much less common and tends to sound literary or poetic. Overall, halo is useful when an image conveys both a visible circle and the impression of something elevated, distinguished, or almost dazzling.
A ring or circle of light surrounding a person's head, an object, or a celestial body; figuratively, an aura of distinction or admiration.
"The saint's head was depicted with a golden halo."
The figurative sense is especially common in expressions suggesting honor, admiration, or exceptional prominence.
To surround something with a halo, or to shine or appear within a halo.
"Mist haloed the streetlights in the harbor."
This verb is relatively uncommon and is most natural in literary, poetic, or descriptive writing.
“Haloes” is also a standard spelling, especially in British English.
"Several halos appeared around the full moon."
A halo around the sun or moon is not painted decoration: it is produced when sunlight or moonlight passes through ice crystals suspended in the air.

Where does halo come from?
The noun entered English in the early 17th century from Latin halo, a borrowing of Ancient Greek hálos, meaning a disk or ring, especially the luminous circle seen around the sun or moon. Greek hálos may be related to háls, meaning salt, from an Indo-European root associated with salt; this connection appears in related English formations such as halide, halogen, and halite. The verb was developed in English from the noun.
