Trans-formable is the ability to be transformed or changed from one form to another. The antonym for trans-formable is immutable, which means unchangeable, fixed or static. This is a term used in various fields like physics, chemistry, biology, and computer science. It denotes the quality of rigidity, which is opposite to flexibility, the essence of trans-formable. Immutable objects or elements are considered permanent, and their alteration or transformation is impossible. The term immutability is very significant in cryptography, where it represents the ability of data to remain fixed, secure, and unalterable, making it ideal for sensitive information.
