blood is thicker than water

used to suggest that family bonds are stronger and more significant than other relationships, indicating that familial ties should be prioritized over friendships or other associations

The origin of the proverb "blood is thicker than water" is debated; however, one of the earliest uses is found in medieval times, with a slightly different version: "The blood of the covenant is thicker than the water of the womb." This earlier form actually implies that bonds formed by choice, such as friendships, can be stronger than those based on family. Over time, the phrase evolved into its current form, which emphasizes the priority of family loyalty and support. The proverb serves as a reminder of the value of family connections, while also highlighting the broader idea that both familial and chosen bonds can be of great importance.
