Morphology

myotonic + dystrophy

The term is a straightforward medical compound: 'myotonic' denotes slow muscle relaxation and 'dystrophy' denotes progressive muscle wasting, so together they describe a disorder with those specific muscle problems. This adjective+noun composition is directly compositional and follows common medical naming patterns (and similar logic exists across many languages), so a learner who knows both constituents can infer the overall meaning.

Etymology

The medical name myotonic dystrophy comes from Greek parts: myo- meaning 'muscle', -tonic meaning 'tight', and dystrophy meaning 'weakening'. This gives the picture of muscles that stay tight and then get weaker, so the term describes a condition where muscles cannot relax and slowly become weak.
