Morphology

rose + bay

Although 'rose' evokes a flowering shrub, 'rose bay' is a conventional plant name whose specific properties (an evergreen, poisonous shrub with clustered fragrant flowers) are not predictable from 'rose' plus the ambiguous element 'bay' (undefined here). Plant common names are often lexicalized and language-specific, so a B1 learner knowing the constituents would be unlikely to infer toxicity, growth habit, or exact identity.

Etymology

Rose bay may come from a simple picture: its flowers look like small roses and its shiny leaves look like those of a bay tree. That's why the name now points to a pretty, showy shrub that is actually poisonous.
