Er Definitions

Webster's 1828 Dictionary

ER, the termination of many English words, is the Teutonic form of the Latin or; the one contracted from wer, the other from vir, a man. It denotes an agent, originally of the masculine gender, but now applied to men or things indifferently; as in farmer, heater, grater. At the end names of places, er signifies a man of the place; Londoner is the same as London-man.
There is a passage in Herodotus, Melpomene, 110, in which the word wer, vir, a man, is mentioned as used by the Scythians; a fact proving the affinity of the Scythian and the Teutonic nations.
"The Scythians call the Amazons Oiorpata, a word which may be rendered, in Greek, menkillers; for oior is the name they give to man, pata signifies to kill." Pata, in the Burman language, signifies to kill; but it is probable that this is really the English beat.

Fifth planet from the sun, the largest nonstellar object in the solar system. It has 318 times the mass and over 1,400 times the volume of earth. Its enormous mass gives it over 2.5 times the gravity of earth at the top of its atmosphere, and exerts strong effects on other members of the solar system. It is responsible for the Kirkwood gaps in the asteroid belt and changes in the motions of comets; it may act as a "sentinel," pulling in bodies that might otherwise collide with other planets. Jupiter has at least 16 moons and a diffuse ring system less than 0.6 mi (1 km) thick, discovered in 1979 by the Voyager spacecraft. The planet is a gas giant, composed mainly of hydrogen and helium in proportions near those of the sun, which it orbits every 12 years at an average distance of 484 million mi (778 million km). Its rapid rotation (9 hours, 55.5 minutes) acts on electric currents to give it the largest magnetic field of any of the planets and causes intense storms, incl. one that has lasted hundreds of years (the Great Red Spot). Little is known of its interior, but it is presumed to have a solid core. Its central temperature is estimated to be 45,000° F (25,000° C); it radiates more heat than it receives from the sun, probably largely heat left over from its formation. Chief god of ancient Rome and Italy. Like his Greek counterpart, Zeus, he was worshiped as a sky god. With Juno and Minerva he was a member of the triad of deities traditionally believed to have been introduced into Rome by the Etruscans. Jupiter was associated with treaties, alliances, and oaths; he was the protecting deity of the republic and later of the reigning emperor. His oldest temple was on the Capitoline Hill in Rome. He was worshiped on the summits of hills throughout Italy, and all places struck by lightning became his property. His sacred tree was the oak.
