When you're looking for another way to describe something happening two times a week, there are a variety of synonyms you can use for "twice-weekly." A few options include "bi-weekly," "semi-weekly," and "every other week." "Bi-weekly" means occurring every two weeks, so it's important to clarify that you mean twice a week in this context. "Semi-weekly" also means occurring twice a week or every other week, but it can also refer to something happening once a week. "Every other week" is more specific in its definition, referring to something occurring every second week, rather than happening twice during a particular week.
