step-brother and haft-brother

I want to know difference between “step-brother” and “Haft-brother”.

A half-brother shares one biological parent with his sibling. A step-brother is a sibling through marriage only. His parent married your parent after you were both born, and thus you share no biological parent.


Thanhduc, please note the correct spelling of ‘half-brother’.[YSaerTTEW443543]
