Trust is the belief or confidence in the reliability, honesty, and integrity of someone or something. It is the foundation of any successful relationship, whether it be personal or professional. Trust can be earned over time through consistent behavior, communication, and shared experiences. For example, trusting a friend to keep a secret or trusting a company to provide a high-quality product.
Very Simple Definition:
Trust is when you believe that someone or something will do what they say they will do. For example, if you trust someone to hold a ladder while you climb, you believe they will do it.
