Biannual is derived from the prefix bi-, which means two, twice, double, doubly, as it comes from the Latin bi-, meaning twice, double, and annual comes from the Old French twelfth century word, annuel, which derives from the Latin annus, year.
The prefix bi- usually means 'every two', so bimonthly means 'every two months'. Semi- means 'half' or 'halfway', so semimonthly means 'every two weeks'. However, bimonthly caâ¦n also mean 'twice a month' - but it is rarely used that way. It is best to remember that bi- is every two and semi- is halfway.. 1 person found this useful.
