Morphology

pestiferous = pest (semi-transparent) = pest + iferous

This sense keeps the historical idea of something 'pest-bearing' and is fairly close to the component meanings, though it is still specialized.

Etymology

Pestiferous comes from Latin pestis ('plague') and -fer ('to carry'), so it literally meant 'plague-carrying'. That's why we still use it for things likely to spread disease or infection.
