Jake

Derived from Jackin (earlier Jankin), a medieval diminutive of JOHN. It is often regarded as an independent name. During the Middle Ages it was very common, and it became a slang word meaning "man". It was frequently used in fairy tales and nursery rhymes, such as 'Jack and the Beanstalk', 'Little Jack Horner', and 'Jack Sprat'. American writers Jack London (1876-1916) and Jack Kerouac (1922-1969) were two famous bearers of this name. It is also borne by American actor Jack Nicholson (1937-).

English form of Iohannes, the Latin form of the Greek name Ιωαννης (Ioannes), itself derived from the Hebrew name יוֹחָנָן (Yochanan) meaning "YAHWEH is gracious". The Hebrew form occurs in the Old Testament (spelled Johanan or Jehohanan in the English version), but this name owes its popularity to two New Testament characters, both highly revered saints. The first is John the Baptist, a Jewish ascetic who is considered the forerunner of Jesus. He baptized Jesus and was later executed by Herod Antipas. The second is the apostle John, who is traditionally regarded as the author of the fourth gospel and Revelation. With the apostles Peter and James (his brother), he was part of the inner circle of Jesus.

This name was initially more common among Eastern Christians in the Byzantine Empire, but it flourished in Western Europe after the First Crusade. In England it became extremely popular: during the later Middle Ages it was given to approximately a fifth of all English boys.

The name (in various spellings) has been borne by 21 popes and eight Byzantine emperors, as well as rulers of England, France, Sweden, Denmark, Poland, Portugal, Bulgaria, Russia and Hungary. It was also borne by the poet John Milton (1608-1674), philosopher John Locke (1632-1704), American founding father and president John Adams (1735-1826), and poet John Keats (1795-1821). Famous bearers of the 20th century include author John Steinbeck (1902-1968), assassinated American president John F. Kennedy (1917-1963), and musician John Lennon (1940-1980).

A name of the Hebrew God, represented in Hebrew by the tetragrammaton ("four letters") יהוה (Yod Heh Vav Heh), which was transliterated into Roman script as Y H W H. Because it was considered blasphemous to utter the name of God, it was only written and never spoken, which resulted in the original pronunciation becoming lost. The name may have originally been derived from the old Semitic root הוה (hawah) meaning "to be" or "to become".

From the Latin Iacobus, which was from the Greek Ιακωβος (Iakobos), which was from the Hebrew name יַעֲקֹב (Ya'aqov). In the Old Testament Jacob (later called Israel) is the son of Isaac and Rebecca and the father of the twelve founders of the twelve tribes of Israel. He was born holding his twin brother Esau's heel, and his name is explained as meaning "holder of the heel" or "supplanter", because he twice deprived his brother of his rights as the firstborn son (see Genesis 27:36). Other theories claim that it is in fact derived from a hypothetical name like יַעֲקֹבְאֵל (Ya'aqov'el) meaning "may God protect".

The English names Jacob and James derive from the same source, with James coming from Latin Iacomus, a later variant of Iacobus. Unlike English, many languages do not have separate spellings for the two names.

In England, Jacob was mainly regarded as a Jewish name during the Middle Ages, though the variant James was used among Christians. Jacob came into general use as a Christian name after the Protestant Reformation. A famous bearer was Jacob Grimm (1785-1863), the German linguist and writer who was, with his brother Wilhelm, the author of 'Grimm's Fairy Tales'.
