immutable
Note: The best way to learn this word is to learn the root mut, which means
“change.” Then you can decode immutable to mean “not changeable.” You will
also realize that mutable = “changeable,” mutation = “a change,” and transmute
= “to change from one form to another.”
“An anvil falling on your head would hurt” is one of the immutable laws of
physics.
