Morphology
pycnidium = pycn + idium
The word is built from specialized Greek combining forms (pycn- + -idium) that are not productive standalone English morphemes, so an average B1 learner cannot derive the meaning from the parts.
Etymology
The word pycnidium comes from the Greek root pykno- meaning 'dense' or 'thick' and the ending -idium meaning 'small'. Think of a small, dense flask that holds spores, so a pycnidium is the tiny, flask-shaped body where certain fungi store and release asexual spores.
