biannual


biannual
biannual, biennial, semiannual, though not synonymous, are frequently confused. The chief source of confusion is biannual, which is used to mean either twice a year or every two years. If no clue to its meaning is given by the text, the reader will often be at a loss to determine the time represented. Because of this ambiguity there is a tendency to avoid biannual and use the other two terms to express the two meanings.
Biennial unequivocally means existing for two years or happening every two years
{

biennial plants

}
{

a biennial convention

}
{

a biennial reunion

}
Semiannual is also unequivocal, since it means half-yearly, that is, twice a year
{

a semiannual publication

}
{

semiannual payments

}
