Morphology
myelin = myel + in
Formed from a technical combining form ('myel-') plus the chemical/noun-forming suffix '-in'; these are specialised morphological elements not recognizable to an average B1 learner, so the meaning cannot be derived from common English base words.
Etymology
Myelin comes from the Greek root myel- and myelos meaning 'marrow'. Bone marrow is a soft, fatty tissue, so that image helps you remember that myelin is a white, fatty covering around nerves that helps messages travel quickly.
