(n.) Any heavenly body which forms the center of a system of orbs.
(n.) The direct light or warmth of the sun; sunshine.
(n.) That which resembles the sun, as in splendor or importance; any source of light, warmth, or animation.
(v. t.) To expose to the sun's rays; to warm or dry in the sun; as, to sun cloth; to sun grain.
