Word Origin & Etymology

Borrowed via Latin from Ancient Greek ἰῶτα (iōta), of Semitic origin and akin to Hebrew יוֹד (yōdh). Because iota is the smallest letter in the Greek alphabet, it came to represent any minuscule amount, popularized by the New Testament passage Matthew 5:18 (often translated as "jot").
