A respectful person thinks carefully about others' feelings and tries not to offend them.
When we talk about being respectful, it usually means being polite and considerate towards other people. You might use the word when describing someone's behavior in a difficult situation – for example, if you witness a disagreement between two friends, but one of them stays calm and doesn't get angry with the other.
Marked or characterized by respect
Example: It is of great importance that you act in a respectful manner towards the duke and duchess.
