Morphology

bilevel = level (transparent) = bi + level

The prefix 'bi-' clearly indicates two levels, and 'level' retains its standard meaning.

Etymology

Bilevel is made of bi- 'two' and level 'a stage or value'. A bilevel image or signal uses only two values, like black and white, so each part is one of those two levels.
