Morphology

Peronospora + tabacina

The genus name 'Peronospora' signals a fungus that harms crops, so a learner who knows that constituent can infer this is a plant pathogen; however the species epithet 'tabacina' is not a common English word and its link to 'tobacco' depends on knowledge of Latin binomial conventions. Because part of the meaning (a fungus) is obvious from the genus but the host-specific sense is not predictable to a B1 learner, the expression is only partially transparent.

Etymology

The name Peronospora tabacina comes from two parts of its scientific name: Peronospora, the fungus group, and tabacina, meaning 'from tobacco'. This fungus makes blue-grey 'mildew' on the underside of tobacco leaves, so the name helps you remember it is the disease that attacks tobacco plants.
