用法筆記

Half brother describes a biological relationship. Do not confuse with stepbrother, which refers to someone whose parent has married your parent — there is no shared blood in that case.

常見錯誤

❌My stepbrother and I have the same father.' (when you mean you share a parent).
✅My half brother and I have the same father.
💡'stepbrother' means no shared blood; use 'half brother' when one parent is shared.
