East

East is a noun, adjective, or adverb indicating direction or geography. East is one of the four cardinal directions or compass points. It is the opposite of west and is perpendicular to north and south.

Etymology

The word east comes from Middle English est, from Old English ēast, which itself comes from the Proto-Germanic *aus-to- or *austra- "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn". This is similar to Old High German *ōstar "to the east", Latin aurora "dawn", and Greek ēōs or heōs.Ēostre, a Germanic goddess of dawn, might have been a personification of both dawn and the cardinal points.

Navigation

By convention, the right hand side of a map is east. This convention has developed from the use of a compass, which places north at the top.

To go east using a compass for navigation, set a bearing or azimuth of 90°.

Cultural

East is the direction toward which the Earth rotates about its axis, and therefore the general direction from which the Sun appears to rise. The practice of praying towards the East is older than Christianity, but has been adopted by this religion as the Orient was thought of as containing mankind's original home. Hence, most Christian churches are oriented towards the east.

Caterpillar

Caterpillar /ˈkætərˌpɪlər/ is the common name for the larvae of members of the order Lepidoptera (the insect order comprising butterflies and moths).

As with most common names, the application of the word is arbitrary and the larvae of sawflies commonly are called caterpillars as well.

Caterpillars of most species are herbivorous, but not all; some are insectivorous, even cannibalistic. Some feed on other animal products; for example clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates.

Caterpillars as a rule are voracious feeders and many of them are among the most serious of agricultural pests. In fact many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpillar are valued as sources of silk, as human or animal food, or for biological control of pest plants.

Etymology

The origins of the word "caterpillar" date from the early 16th century. They derive from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose: cate, cat (from Latin cattus) + pelose, hairy (from Latin pilōsus).
