Morphology

myotonic + muscular + dystrophy

The term is a literal, technical composition: 'myotonic' (delayed muscle relaxation) + 'muscular' (relating to muscles) + 'dystrophy' (progressive muscle wasting) directly describe a muscle-wasting condition with myotonia. This adjective+noun medical construction is compositional and follows common cross-linguistic medical naming patterns, so a learner who knows the constituent meanings can infer the overall condition.

Etymology

Myotonic muscular dystrophy comes from its parts: myotonic means muscles that 'stay tight' or have trouble relaxing, and muscular dystrophy means muscles slowly 'get weaker' and waste away. So the name describes a condition often passed down in families where muscles slowly weaken and also have trouble letting go, which explains symptoms like difficulty releasing a grip.
