Dissimilation (also called dissimilatory change) is a sound change in which one sound becomes less similar than another, usually adjacent, sound: Latin peregrinus > French pelerin 'pilgrim', Eng. pilgrim. Dissimilation is the opposite of assimilation.
A famous example of dissimilation is the dissimilation of aspirates in Greek and Sanskrit known as Grassmann's Law.
