J and I were the same letter once. Around 1500 in Middle German language they distinguished the sound of I and J. Later on Romance languages further
enhanced the different sounds. Due to once being the same letter as I the letter J has received little use.
The letter J is the fourth least used letter in words however the letter J is common in proper nouns, especially personal names.
