J
10th letter of the English alphabet, pronounced "jay," as in "kay" for -k-, but formerly written out as jy, rhyming with -i- and corresponding to French ji.

One of the most stable English letters (it has almost always the same sound), it is a latecomer to the alphabet and originally had no sound value. The letter itself began as a scribal modification of Roman -i- in continental Medieval Latin. The scribes added a "hook" to small -i-, especially in the final position in a word or roman numeral, to distinguish it from the strokes of other letters. The dot on the -i- (and thus the -j-) and the capitalization of the pronoun I are other solutions to the same problems.

In English, -j- was used as a roman numeral throughout Middle English, but the letter -y- was used to spell words ending an "i" sound, so -j- was not needed to represent a sound. Instead, it was introduced into English c. 1600-1640 to take up the consonantal sound that had evolved from the Roman i- since Late Latin times. In Italian, g- was used to represent this, but in other languages j- took the job. This usage is attested earliest in Spanish, where it was in place before 1600.
No word beginning with J is of Old English derivation. [OED]
English dictionaries did not distinguish words beginning in -i- and -j- until 19c., and -j- formerly was skipped when letters were used to express serial order.

In Latin texts printed in modern times, -j- often is used to represent Latin -i- before -a-, -e-, -o-, -u- in the same syllable, which in Latin was sounded as the consonant in Modern English you, yam, etc., but the custom has been controversial among Latinists:
The character J, j, which represents the letter sound in some school-books, is an invention of the seventeenth century, and is not found in MSS., nor in the best texts of the Latin authors. [Lewis]
In English words from Hebrew, -j- represents yodh, which was equivalent to English consonantal y (hence hallelujah) but many of the Hebrew names later were conformed in sound to the modern -j- (compare Jesus).

-Baruch 2:26-35
26 And the house which is called by thy name hast thou laid waste, as it is to be seen this day, for the wickedness of the house of Israel and the house of Juda.
27 O Lord our God, thou hast dealt with us after all thy goodness, and according to all that great mercy of thine,
28 As thou spakest by thy servant Moses in the day when thou didst command him to write the law before the children of Israel, saying,
29 If ye will not hear my voice, surely this very great multitude shall be turned into a small number among the nations, where I will scatter them.
30 For I knew that they would not hear me, because it is a stiffnecked people: but in the land of their captivities they shall remember themselves.
31 And shall know that I am the Lord their God: for I will give them an heart, and ears to hear:
32 And they shall praise me in the land of their captivity, and think upon my name,
33 And return from their stiff neck, and from their wicked deeds: for they shall remember the way of their fathers, which sinned before the Lord.
34 And I will bring them again into the land which I promised with an oath unto their fathers, Abraham, Isaac, and Jacob, and they shall be lords of it: and I will increase them, and they shall not be diminished.
35 And I will make an everlasting covenant with them to be their God, and they shall be my people: and I will no more drive my people of Israel out of the land that I have given them.
