West

West is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth. The word "west" is a Germanic word passed into some Romance languages (ouest in French, oest in Catalan, ovest in Italian, oeste in Spanish and Portuguese). As in other languages, the word formation stems from the fact that west is the direction of the setting sun in the evening: 'west' derives from the Indo-European root *wes reduced from *wes-pero 'evening, night', cognate with Ancient Greek ἕσπερος hesperos 'evening; evening star; western' and Latin vesper 'evening; west'. Examples of the same formation in other languages include Latin occidens 'west' from occidō 'to go down, to set' and Hebrew מַעֲרָב maarav 'west' from עֶרֶב round 'evening'. West is sometimes abbreviated as W. To go west using a compass for navigation (in a place where magnetic north is the same direction as true north) one needs to set a bearing or azimuth of 270°. West is the direction opposite that of the Earth's rotation on its axis, and is therefore the general direction towards which the Sun appears to constantly progress and eventually set. This is not true on the planet Venus, which rotates in the opposite direction from the Earth (retrograde rotation). To an observer on the surface of Venus, the Sun would rise in the west and set in the east although Venus's opaque clouds prevent observing the Sun from the planet's surface. In a map with north at the top, west is on the left. Moving continuously west is following a circle of latitude. Due to the direction of the Earth's rotation, the prevailing wind in many places in the middle latitudes (i.e. between 35 and 65 degrees latitude) is from the west, known as the westerlies. The phrase "the West" is often spoken in reference to the Western world, which includes the European Union (also the EFTA countries), the United Kingdom, the Americas, Israel, Australia, New Zealand and (in part) South Africa.
