Morphology

nux + vomica

“Nux vomica” is a Latin botanical/binomial name made of non‑English lexical items that a B1 learner will not know; the constituent forms carry no transparent, everyday meaning in English. Its sense as a specific, toxic medicinal preparation (containing strychnine/brucine) is technical and cannot be derived from the parts without specialist or prior lexical knowledge, so it is idiomatic/opaque to learners.

Etymology

Nux vomica comes from old Latin words nux and vomica, meaning 'nut' and 'to vomit', because the tree's seeds are poisonous and can make people sick. Herbalists long ago made a medicine from tiny amounts of these seeds, so today nux vomica refers to a seed-based medicine that can be toxic if misused.
