Morphology

myotonia = tone (semi-transparent) = myo + ton + ia

Formed from the combining form 'myo-' (muscle) + 'tone' + the noun-forming suffix '-ia'; clear to those familiar with medical prefixes but not to general B1 learners.

Etymology

The word myotonia breaks into Greek parts: myo- meaning 'muscle' and tonia, from tonos, meaning 'tension' or 'tone'. So myotonia means 'muscle tension' that lasts too long, which is why muscles stay tight and relax slowly.
