Definition of credible

The word "credible" originates from the Latin word "credibilis," which means "worthy of being believed." This Latin word is a combination of "credere," meaning "to believe," and the suffix "-ilis," which forms an adjective indicating quality or capacity. The word "credible" has been in use in English since the 15th century, initially used to describe something that is worthy of trust or belief. Over time, the meaning of the word has evolved to encompass notions of reliability, trustworthiness, and integrity. In modern English, "credible" is often used to describe information, sources, or individuals that are trustworthy and convincing. For example, a "credible witness" would be someone whose testimony is deemed reliable and believable.
