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.
Usage notes. Like bimonthly and biennially, but unlike biannually, in the adjective and adverb senses, the prefix bi- applies to the week rather than to the events that occur, therefore giving the sense of âevery two weeksâ. Since the term is also used in the UK to mean âtwice a weekâ, it is ambiguous there. In British English, for the sake of clarity, it is advisable to use one of the synonyms instead. Furthermore, in some English speaking regions, the term fortnightly is also commonly used to describe an event happening once every two weeks. Synonyms
