Morphology

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

The word is built from 'pest' + '-iferous', but the sense 'troublesome' is a metaphorical extension rather than a fully literal combination.

Etymology

Pestiferous comes from Latin pestis ('plague') and -fer ('to carry'), and is built on the same pest you know in English. So it originally meant 'plague-carrying', and that's why it can describe something very annoying or troublesome that keeps causing problems.
