The words iota and jot share a lot more than just a common meaning—both ultimately derive from the same word. When Latin scholars transcribed the Greek name of the ninth letter of the Greek alphabet, they spelled it as either iota or jota (the letters i and j were simply variants of each other), and these spellings eventually passed into English as iota and jot. Since the Greek letter iota is the smallest letter of its alphabet, both words eventually came to be used in reference to very small things.
