Morphology

Puccinia + graminis

This binomial is compositionally transparent: Puccinia identifies the genus (a fungus) and graminis is the Latin epithet meaning 'of grasses' (from gramen 'grass'), so a learner who knows both constituents can infer it is a fungus affecting grasses/wheat. Scientific Latin naming is regular and cross-linguistically consistent, making the overall meaning derivable from the parts.

Etymology

Puccinia graminis comes from scientific naming. Puccinia is the name used for 'rust' fungi and graminis is Latin for 'of grass', so the name literally points to a rust that attacks grasses like wheat.
