iota subscript

Noun

 * 1)  A small iota written below an alpha, eta or omega – e.g. in  – representing a vocalic offglide that was pronounced in early Ancient Greek, but later became silent; invented in the Middle Ages in order to mark those vowels which would originally have had such an offglide.
