Your reputation is the general belief or opinion that other people have about you. If you are considered trustworthy and kind, you have a good reputation.
Reputation comes from the Latin word reputationem, which means "consideration." It's how people consider, or label, you — good or bad. The noun reputation can also mean "being known for having a specific skill or characteristic." For example, if you have a reputation in snow shoveling, your phone will soon be ringing off the hook with your lazy neighbors calling.
