orb n.

mid-15c., "sphere, globe, something spherical or circular, orbit of a heavenly body," from Old French orbe "orb, globe" (13c.) and directly from Latin orbem (nominative orbis) "circle, disk, ring, hoop, orbit," probably related to orbita "wheel track, rut," a word of unknown and much-disputed origin. Watkins suggests a connection with the root of orchid. De Vaan suggests *horbi- "turning thing."

A three-dimensional extension of a word originally describing two-dimensional shapes. The ancient astronomical sense is in reference to the hollow "spheres" that carried each of the planets and the stars through their heavenly motions in the Ptolemaic system. Used poetically of the earth, sun, or moon from 1590s; used rhetorically of the eye from 1650s. As a verb from c. 1600.

Orb-weaver in reference to spiders that make webs formed of lines radiating from a central point (as distinguished from tube- or tunnel-weavers) is recorded from 1889.

Entries linking to orb orchid n. 1845, introduced by John Lindley in the third edition of "School Botany," from Modern Latin Orchideæ (Linnaeus), the plant's family name, from Latin orchis, a kind of orchid, from Greek orkhis (genitive orkheos) "orchid," literally "testicle," from PIE *h(o)rghi-, the standard Indo-European word for "testicle" (source also of Avestan erezi, Armenian orjik'"testicles," Old Irish uirge, Hittite arki- "testicle," Lithuanian eržilas "stallion"). The plant so called because of the shape of its root; Greek orkhis also was the name of a kind of olive, also so called for its shape. Earlier in English in Latin form, orchis (1560s), and in Middle English it was ballockwort (c. 1300; see ballocks). The modern word is marred by an extraneous -d- in an attempt to extract the Latin stem.
