What year did the letter J come?

The letter "J" was not added to the English alphabet as a distinct letter until the early 17th century, although the process of differentiation began earlier.

• The Italian grammarian Gian Giorgio Trissino is credited with the first explicit distinction between "I" and "J" in his work "Epistola del Trissino de le lettere nuovamente aggiunte ne la lingua italiana" in 1524. However, this distinction did not immediately become widespread234.

• In English, the clear distinction between "I" and "J" in writing began to take hold in the early 17th century. For example, the King James Bible's 1629 edition was one of the first major texts to use "J" as a distinct letter124.

So, while the idea of separating "I" and "J" emerged in 1524, the letter "J" became a standard part of the English alphabet in the early 17th century.
