Warmup 11/8/2013 What does the phrase “Blood is thicker than water” mean? In the beginning, it meant something to the effect of “a bond or covenant I’ve made with someone I’ve shed or shared blood with (sometimes literally) is stronger than one I have with someone I’ve shared the womb with.” Obviously today it’s interpreted the other way, that the bond between family members or blood relations is stronger than one between people only connected by water.
