Am I A Step Or Half Sister

[Biccylova]

Can anyone tell me the difference between a step sister or brother and a half sister or brother?

[Islay]

Step - no shared blood
Half - you share either a mother or father with another child

[Cloverjo]

Half-siblings share one parent. Step-siblings have one parent married to the other's parent, with no genetic link.

Step sibling does not have to be related by blood but half sibling does ?

[Prudie]

half sibling always shares one common blood parent (ie same mother or father). Step is when they are children of someone your parent has married.

Thank you all, that's something that always confused me,
