Usage

What does brotherly mean? Brotherly is an adjective that most commonly means like a brother. It’s especially used in a positive way to describe someone as being loyal, supportive, and protective—like a good brother who loves and cares about you. Describing someone as brotherly sometimes implies that they’re like an older brother who can give good advice. The word fraternal can be used to mean the same thing, but it can also be used in a more neutral way that doesn’t imply these positive things. Brotherly is most often used to describe brothers themselves and the brotherly things they do, but it can be applied to someone who’s not a brother, as in I don’t have a brother, but I always rely on Joe for brotherly support. It’s sometimes used in a more general way to describe behavior based on treating others with respect and affection, as if they were family members. The word neighborly is similar. Brotherly can also be used as an adverb meaning in the manner of a brother. Brotherly is one of many similar terms based on family relations, including sisterly, motherly, fatherly, grandmotherly, and grandfatherly. Example: I’m lucky that my brothers and I have always shared a brotherly affection—we all support each other.
