Sisterhood is the special bond between sisters, or a feeling of connection and support among women and girls who stand up for each other like sisters would. When two girls are actual sisters, their sisterhood includes all the shared experiences of growing up in the same family: the inside jokes, the arguments over borrowed clothes, the late-night conversations, and the knowledge that someone has known you your whole life.

But sisterhood extends beyond biology. When a group of girls forms a close friendship, supporting each other through challenges and celebrating each other's successes, they create their own kind of sisterhood. A soccer team might develop a strong sense of sisterhood, where teammates encourage each other and refuse to let anyone feel left out. Women who work together for a common cause, like scientists collaborating on a research project or activists fighting for a shared goal, often describe their connection as sisterhood.

The word captures something specific: the loyalty, understanding, and fierce protectiveness that sisters often share. In a true sisterhood, members look out for each other, speak up when someone is being treated unfairly, and find strength in their connection. The concept reminds us that some of our most powerful relationships come from standing together and treating each other like family, whether we share the same parents or not.
