Usage

What does sisterly mean? Sisterly is an adjective that most commonly means like a sister. It’s especially used in a positive way to describe someone as being loyal, supportive, and protective—like a good sister who loves and cares about you. Describing someone as sisterly sometimes implies that they’re like an older sister who can give good advice. Sisterly is most often used to describe sisters themselves and the sisterly things they do, but it can be applied to someone who’s not a sister, as in I don’t have a sister, but I always rely on Jane for sisterly support. Sisterly can also be used as an adverb meaning in the manner of a sister. Sisterly is one of many similar terms based on family relations, including brotherly, motherly, fatherly, grandmotherly, and grandfatherly. Example: I’m lucky that my sisters and I have always shared a sisterly affection—we all support each other.
