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'.
[1] 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 (erev) 'evening'.
[4][5] 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.
During the Cold War "the West" was often used to refer to the NATO camp as opposed to the Warsaw Pact and non-aligned nations.
In Ancient Egypt, the West was considered to be the portal to the netherworld, and is the cardinal direction regarded in connection with death, though not always with a negative connotation.
