A preheritance is money, a house, or other family property that you get while your parents (or another relative) are still alive, not after they die. People do it so the family hopes to pay less tax on what would later be an inheritance. The word is quite new and a little jokey — a newspaper blend, not a lawyer’s word. In a law office you would hear lifetime gift instead. Though actually, it does not always save tax the way families expect: governments keep changing the rules, and a big gift while someone is alive can be taxed too. You will meet this word in money stories and family-planning talk, not in everyday chat.
