For example, a reliable car starts every time and gets you to your destination without breaking down. In relationships, a reliable friend is someone you can count on for support and honesty. Reliability is important in various aspects of life, including work, where a reliable employee completes tasks on time and follows through on commitments. Overall, reliability fosters trust and stability in both personal and professional settings.
