What does unshakable mean?
Unshakable means firm, steady, and impossible to dislodge or unsettle. It is especially used for beliefs, commitments, principles, loyalty, and personal qualities such as determination or courage. Someone described as unshakable is not merely temporarily confident; they remain committed despite pressure, criticism, difficulty, or uncertainty. The word can also apply to support that is exceptionally secure or to a person's calmness in a crisis. Its force comes from combining the prefix un-, meaning “not,” with the idea of something being physically shaken. As a result, unshakable often suggests a stability that is deeper and more enduring than ordinary firmness. It is a common choice in formal writing, journalism, speeches, and professional contexts, and it can also appear in everyday descriptions of personal conviction.
