Iota Meaning

Iota is often used to represent a very small quantity, leading to the phrase "not one iota" meaning "not the slightest amount." In physics, it's used as the unit vector for the y-axis in the complex plane. The iota subscript in Greek diacritics changes the pronunciation of vowels. In biochemistry, iota is used in naming some types of carrageenan, a food additive.
