Morphology

biannual = annual (transparent) = bi + annual + ann

The prefix 'bi-' clearly indicates 'two' or 'twice', making the meaning of 'biannual' as 'twice a year' directly derivable from 'annual'.

Etymology

Biannual comes from bi- 'two' and annual 'year', so it means 'two times a year'. A helpful memory is bicycle, where bi- also means two, and annual is like an 'annual' event that happens each year.
