Morphology

Mercurialis + perennis

This is a Latin binomial: 'Mercurialis' names the genus (dog's mercury) and 'perennis' is the Latin root meaning 'perennial'. If a learner knows both constituents and botanical naming conventions, they can infer it refers to a perennial Mercurialis (a perennial plant). However, the form is a technical proper name in Latin and unfamiliar to most B1 learners, so the meaning is only partly predictable.

Etymology

Mercurialis perennis, often called dog's mercury, has a name from old medicine stories: one simple idea is that people used 'mercury' in remedies and adding 'dog' marked a common or 'less useful' version. Because this low, green plant spreads like a carpet in the woods and is actually 'poisonous', the name stuck to warn people.
