The word “infallible” refers to something or someone that is incapable of making mistakes or being wrong. It suggests a high degree of reliability, accuracy, or certainty.
Interesting fact: The term “infallible” is often associated with religious contexts, particularly in relation to the Pope’s infallibility in matters of doctrine and faith within the Catholic Church. However, outside of religious contexts, the word can also be used to describe anything that is considered flawless or error-free.
