Morphology

immutable = mutable (transparent) = im + mutable

The adjective is formed by negating the adjective 'mutable' with the productive negative prefix 'im-', yielding 'not changeable', which is directly inferable.

Etymology

The word immutable comes from the parts in- ('not') and mutare ('to change'), the same root you see in mutate and mutation. So an immutable thing is 'not able to be changed' and stays the same over time.
