halfsibling
One parent shared
A halfsibling is a brother or sister who shares one biological parent with you but not both—either the same mother or the same father.
The relationship is distinguished from full siblings (sharing both parents) and stepsiblings (sharing no biological parent).
Usually written as two words: half sibling or half-sibling.
