/juːˈfreɪtiːz/
noun
1.
a river in SW Asia, rising in E Turkey and flowing south across Syria and Iraq to join the Tigris, forming the Shatt-al-Arab, which flows to the head of the Persian Gulf: important in ancient times for the extensive irrigation of its valley (in Mesopotamia). Length: 3598 km (2235 miles)

Old English Eufrate, from Greek Euphrates, from Old Persian Ufratu, perhaps from Avestan huperethuua “good to cross over,” from hu- “good” + peretu- “ford.” But Kent says “probably a popular etymologizing in O.P. of a local non-Iranian name” [“Old Persian,” p.176]. In Akkadian, purattu.

Hebrew, Perath; Assyrian, Purat; Persian cuneiform, Ufratush, whence Greek Euphrates, meaning “sweet water.” The Assyrian name means “the stream,” or “the great stream.” It is generally called in the Bible simply “the river” (Ex. 23:31), or “the great river” (Deut. 1:7). The Euphrates is first mentioned in Gen. 2:14 as one of the rivers of Paradise. It is next mentioned in connection with the covenant which God entered into with Abraham (15:18), when he promised to his descendants the land from the river of Egypt to the river Euphrates (comp. Deut. 11:24; Josh. 1:4), a covenant promise afterwards fulfilled in the extended conquests of David (2 Sam. 8:2-14; 1 Chr. 18:3; 1 Kings 4:24). It was then the boundary of the kingdom to the north-east. In the ancient history of Assyria, and Babylon, and Egypt many events are recorded in which mention is made of the “great river.” Just as the Nile represented in prophecy the power of Egypt, so the Euphrates represented the Assyrian power (Isa. 8:7; Jer. 2:18). It is by far the largest and most important of all the rivers of Western Asia. From its source in the Armenian mountains to the Persian Gulf, into which it empties itself, it has a course of about 1,700 miles. It has two sources, (1) the Frat or Kara-su (i.e., “the black river”), which rises 25 miles north-east of Erzeroum; and (2) the Muradchai (i.e., “the river of desire”), which rises near Ararat, on the northern slope of Ala-tagh. At Kebban Maden, 400 miles from the source of the former, and 270 from that of the latter, they meet and form the majestic stream, which is at length joined by the Tigris at Koornah, after which it is called Shat-el-Arab, which runs in a deep and broad stream for above 140 miles to the sea. It is estimated that the alluvium brought down by these rivers encroaches on the sea at the rate of about one mile in thirty years.
