Morphology

order + Pycnogonida

The phrase combines 'order' (a taxonomic grouping) with the taxon name 'Pycnogonida' (marine arthropods), so its meaning — the taxonomic order containing Pycnogonida — is directly and compositionally derivable from the parts. Although domain-specific, this noun + taxon pattern is transparent and common across languages, so a B1 learner who knows both constituents would understand it.

Etymology

Order Pycnogonida gets its name from Greek words: pycno- meaning 'thick' and -gonida meaning 'knee', a vivid image of their strong leg joints. These long-legged sea creatures are often called 'sea spiders', so the name helps you picture their heavy-looking leg joints and remember the group.
