What is my half-sister's grandson to me?
Your half-sister's grandson is your half-great-nephew. Your half-sister shares one parent with you, and their grandson sits two generations further down the same line. From the other side, you are their half-great-aunt or half-great-uncle — each further generation down adds another 'great' to both titles.
