Morphology

Rhus + quercifolia

This is a Latin binomial (genus + specific epithet). While 'Rhus' signals a sumac (so a plant), the epithet 'quercifolia' is not a common English word (missing from the dictionary) and the species-specific information that it is poisonous and causes a rash cannot be inferred from the parts. A B1 learner who knows the listed constituent words would therefore not reliably derive the full meaning.

Etymology

Rhus quercifolia comes from old Latin words: Rhus meaning 'sumac' and quercifolia meaning 'oak-leaved' because its leaves look like small oak leaves. That picture — a sumac with oak-like leaves — helps you remember this poisonous shrub that can give a skin rash if you touch it.
