gentlemanly

Originally, "gentlemanly" was connected to the idea of a gentleman, which in earlier times could refer to a man of high social position. Over time, the word came to focus much more on behavior than on class or birth. Today, "gentlemanly" usually describes a man whose actions are polite, respectful, considerate, and honorable. It suggests good manners, calm behavior, and a willingness to treat other people well.

The word is still mainly used for men, because it comes directly from "gentleman." You might call someone gentlemanly if he helps others without making a show of it, speaks in a calm and respectful way, behaves fairly during an argument, or shows care for someone's comfort or feelings. The idea is not just formal politeness, but also decency and self-restraint.

The term often has an old-fashioned tone and can bring to mind traditional ideas of courtesy, such as standing when someone enters, offering a seat, or speaking with special care. Even so, it is still used in modern English when someone behaves in a notably respectful and honorable way. A gentlemanly response to conflict, for example, would be calm and fair rather than insulting or aggressive.

So while the word has old roots, its modern meaning is simple: it describes behavior that is polite, decent, respectful, and worthy of admiration.
