Amoeba

We've been pronouncing this word incorrectly: it's not ameeba, it's amoybay. See here: 'early naturalists referred to Amoeba as the Proteus animalcule after the Greek god Proteus who could change his shape. The name "amibe" was given to it by Bory de Saint-Vincent, from the Greek amoibè (αμοιβή), meaning change.'
