Definitions
noun
- a brother who has only one parent in common with you
Examples
It should be appreciated that brothers, sisters, stepbrothers and stepsisters are not entitled to any share of the inheritance when children and parents of the deceased are alive.
Paragraph of the definition then goes on to say that, to avoid doubt, it includes brothers, stepbrothers, stepsisters, step-parents or guardians, grandparents, and so forth.
If so, realize your stepbrother has to adjust to this new family too.
