Morphology

poison + ivy

The meaning is directly derivable from 'poison' (a harmful substance) + 'ivy' (a plant): a B1 learner who knows both words can infer it is an ivy that is poisonous and likely to cause harm such as a rash. This noun–noun compound follows a regular compositional pattern (e.g. hiedra venenosa, lierre vénéneux), so it is readily understandable without prior exposure.

Etymology

The skin reaction called poison ivy is named after the plant because its oil can 'poison' the skin and cause an itchy 'rash'. So when people say poison ivy they can mean the rash as well as the plant.
