half-sister
One parent shared
A half-sister is a sister with whom you share only one biological parent—either the same mother or the same father, but not both.
My half-sister and I have the same dad but different moms.
The relationship is distinguished from full siblings (who share both parents) and stepsiblings (who share no biological parent).
