Morphology
Dioscorea + alata
This is a Linnaean binomial combining the genus name 'Dioscorea' (a tropical genus of yams) with a species epithet; a learner who knows those constituents will readily infer it denotes a specific kind of Dioscorea (i.e. a species of yam with the described tuber). Taxonomic name formation is compositional and cross-linguistically recognizable, and even if the Latin adjective 'alata' is not fully transparent semantically, its role as an identifier makes the overall meaning predictable.
Etymology
Dioscorea alata gets its name from two parts: Dioscorea probably honors an old Greek doctor, Dioscorides, who wrote about plants, and alata is a Latin word meaning 'winged', used for thin, wing-like parts on the stem or leaf. So the name helps you remember this particular yam, the starchy and sometimes purple edible root it refers to.
