"Semiannually" means happening twice a year, or every six months. Think of it as the opposite of "annually," which happens once a year. It's a regular occurrence, just spread out over two points in the year. For example, you might get a report card semiannually, once in January and again in June. It suggests a consistent but not overly frequent pattern. It's a common term used in business, finance, and education.
