Morphology

Neisseria + meningitidis

The compound is a Linnaean binomial: 'Neisseria' indicates a bacterial genus and the species epithet 'meningitidis' is transparently related to 'meningitis', so a learner who recognises both parts can infer it is a bacterium associated with meningitis. However, species names use Latinized morphology and taxonomic conventions that are specialized, so an average B1 learner without biomedical or Latin knowledge would not reliably derive the full meaning.

Etymology

Neisseria meningitidis takes its name from the doctor Albert Neisser who first found the germ, and the first part, Neisseria, is his name while the second part, meningitidis, points to the thin covers around the brain called 'meninges'. That's why the full name tells you it is a germ that can make those covers swell in 'meningitis' and cause that illness.
