corona

Meanings

1. 1
   noun

   A large, round, pendent chandelier, with spikes around its upper rim to hold candles or lamps, usually hung from the roof of a church.

   The magnificent bronze corona, or luminaria, which still hangs in the central octagon, shews the skill of the workmen in bronze of that period.

2. 2
   noun

   An upper or crownlike portion of certain parts of the body.

   Is it probable that this depression has arisen from the distorting effect of some form of head dress, similar perhaps to that which is still applied to the heads of infants in various parts of France, as described by Drs. Foville and Lunier? This consists of a neckerchief passed twice round the head from the corona either to the back of the neck, when the resulting deformity (which is that of the Charlcombe skull) is designated annular by Dr. Gosse; or is carried under the chin and jaw, when it is termed bilobed by the same writer.

3. 3
   noun

   The large, flat, projecting member of a cornice which crowns the entablature, situated above the bed moulding and below the cymatium.

   The cornice only is carried around the room at the ceiling, and in the staircase hall only the cymatium and corona of the cornice; but over the archway, supported by a colonnade of four fluted round columns, a complete entablature with nicely worked classic detail is employed and given added emphasis by several inches' projection into the reception hall.

4. 4
   noun

   The luminous plasma atmosphere of the Sun (the solar corona) or other star, extending millions of kilometres into space, most easily seen during a total solar eclipse.

   My investigations seem to prove conclusively that the theoretical corona is caused by light emitted and reflected from streams of matter ejected from the Sun by forces which, in general, act along lines normal to the surface. These forces are most active near the center of each Sun-spot zone.

5. 5
   noun

   An oval-shaped astrogeological feature, present on both the planet Venus and Uranus's moon Miranda, probably formed by upwellings of warm material below the surface.

   The area density of impact craters on the surfaces of the coronas suggests that the episode of tidal heating occurred approximately one billion years ago[…].

6. 6
   noun

   Any luminous or crownlike ring around an object or person.

   It looked like a miniaturized version of Hiroshima. Fires burned here and there. […] His once and future presidential palace was a crater ringed by a corona of flaming debris.

7. 7
   noun

   Any appendage of an organism that resembles a crown or corona (sense 4.1).

   [page 317] The lower jaw conſiſts of one large bone, with fore and hinder part, and five proceſſes; viz. two Condyles[…], two proceſſes of the Corona[…], and one proceſs of the chin […] [page 318] [T]his Sinus deſcends obliquely nine inches from the neck of the condyle, till it comes to the root of the teeth[…]; which ſpace does not appear ſo large in the figure, becauſe of the poſition of the jaw; and from the fore-part of the Coronæ backwards, till the jaw become thick, five inches and ⅓; […]

8. 8
   noun

   A luminous appearance caused by corona discharge, often seen as a bluish glow in the air adjacent to pointed metal conductors carrying high voltages.

   An appearance of a corona may produce useful or undesirable effects. For instance, a corona arising spontaneously around high-voltage wires of an electrical power transmission line results in a loss of electrical energy. On the other hand, coronas are widely used in many practical applications like dust collection with electrical precipitators, atmospheric pressure non-thermal plasma surface treatment of polymers, cleaning of exhausted gases, etc.

Etymology

All ultimately from Latin corōna (“crown”). * (Corona, California): From Spanish corona (“crown, wreath”), chosen to play upon a unique feature of the city, the one-mile diameter drive that circled the center of the town. * (Corona, New Mexico): * (Corona, South Dakota): May be a transfer from Corona, Queens. * (Corona, Queens): One theory is that it was renamed by music producer Benjamin W. Hitchcock, a developer who renamed the area in 1872 and sold off land for residential development. Another theory is that real estate developer Thomas Waite Howard, who became the first postmaster in 1872,…
