There are several words that stem from the Latin root “mutare,” meaning “to change.” “Mutate” means “to undergo or cause to undergo mutation,” and “mutation” itself means “a major change.” If you add the Latin prefix “im-,” meaning “not,” you get the unchanging power of “immutable.” Other “mutare”-related words include “permute,” meaning “to change the order or arrangement of”; “transmute,” meaning “to change or alter in form, appearance, or nature”; and their noun forms, “permutation” and “transmutation.”
