A more thorough explanation:

Definition: Credibility means that something or someone is believable and can be trusted. It is the quality that makes people believe in something or someone.

Examples:

• A doctor who has many years of experience and a good reputation has credibility when giving medical advice.
• A news article that has been fact-checked and comes from a reliable source has credibility.
• A witness in a court case who has no reason to lie and has a good memory has credibility when giving testimony.

These examples illustrate how credibility is important in different situations. People are more likely to believe and trust someone or something that has credibility. It is important to establish credibility in order to be taken seriously and to have influence.
