The letter “J” is notable for being the most recent addition to the English alphabet. Initially, in the Latin alphabet, there was no clear distinction between the letters “I” and “J,” and they were used interchangeably to denote the same sound. It was only during the 16th century that “J” emerged as a separate and distinct letter, a result of the efforts of Renaissance scholars who refined its usage to represent the consonantal sound it signifies today, as seen in words like “joy” or “jump.” This evolution marked the inclusion of “J” as the final addition to the 26-letter English alphabet.
