Morphology

tobacco + mosaic + virus

The compound is fully compositional: 'tobacco' names the host plant, 'mosaic' describes the characteristic leaf mottling, and 'virus' identifies the pathogen, so a learner who knows those words can infer it denotes a virus that causes mosaic-like symptoms in tobacco (and similar plants). This follows standard modifier+noun composition and is cross-linguistically transparent, even if the term is more technical than everyday vocabulary.

Etymology

The name tobacco mosaic virus comes from the way it makes tobacco leaves look like a mosaic, a 'patchy' pattern of light and dark. So today tobacco mosaic virus means the small virus that infects those plants and makes that patchy leaf pattern.
