Morphology

Pteridium + aquilinum

This is a scientific binomial: knowing 'Pteridium' (a genus of bracken ferns) lets a learner infer the phrase names a type of fern, so part of the meaning is transparent. However, the species epithet 'aquilinum' is Latin and not semantically transparent to a typical B1 learner (and its dictionary definition is missing here), so the specific attributes of the plant are not derivable from the parts.

Etymology

Pteridium aquilinum may come from old Greek and Latin words: Pteridium meaning 'feather' and aquilinum meaning 'eagle'. Its long, feather-like leaves spread wide like an eagle's wing, so this image helps you remember it as the large bracken fern found in many places.
