adjective

immutable

ih-MYOO-tuh-bul/ɪˈmjuːtəbl/

Not able to be changed.

The engraved words seem immutable through sunshine and rain.

A deeply engraved stone inscription remains unchanged through sunshine and rain, symbolic permanence, no tiny writing.
Etymology

The change root and ability ending make “changeable,” which the negative prefix reverses. Something immutable is therefore not merely unchanged so far, but unable to be altered.
