Morphology

Xiphosurus + polyphemus

This is a Linnaean scientific binomial composed of Latin/Greek elements that are not ordinary English words, so a B1 learner who 'knows the constituent words' would not have productive knowledge of these morphemes. The label functions as an arbitrary taxonomic name rather than a compositional phrase whose meaning ('Atlantic horseshoe crab') can be derived from its parts. Any etymological hints (e.g. xipho- or Polyphemus) require specialist or classical-language knowledge beyond B1, making the expression non-compositional for typical learners.

Etymology

The name Xiphosurus polyphemus may come from Greek words that describe how it looks. The part xiphos means 'sword' for its long pointed tail, and polyphemus suggests a big, unusual creature, so the name fits this large horseshoe-shaped crab with a stiff tail.
