The letter J first came about as a variation of the letter i, originally used to clarify the last in a sequence of Roman numerals—so iii, for 3, might once have been written iij to avoid any confusion with whatever followed. Over time, it began to establish itself as a letter in its own right, with its own distinct sound, but it wasn’t until after the Norman Conquest of England in 1066 that J first began to appear in English words: Scribes borrowed it into English from French in the early Middle Ages as a replacement for the initial dzh sound (that’s the voiced palate-alveolar affricate, should you want to know), found in words like judge and jump. Even today, J is much more likely to be found in the initial position than it is anywhere else in a word.

Overall, though, J remains a fairly rare letter in English—you can expect to find it in just 0.16 percent of the words in a dictionary, including the 35 joyous J words here.
