infallible

adjective

Definition: 1. incapable of making a mistake; 2. never failing

Synonyms: perfect, reliable, faultless, flawless

Antonyms: flawed, imperfect, unsound, weak

Tips: Infallible is derived from the Latin in-, "not," and fallibilis, "liable to err, deceitful." Infallible is really a more sophisticated way of saying "perfect and incapable of mistakes." Infallible is usually used to point out that nobody is perfect: "Do you know anyone who is infallible (perfect, incapable of making a mistake or error)?"
