Morphology

amyotrophic = myotrophic (opaque) = a + myo + troph + ic

The prefix 'a-' negates 'myotrophic', but the medical context and specific meaning are not obvious to learners.

Etymology

Amyotrophic comes from parts meaning a- 'without', myo- 'muscle', and -trophic 'feeding'. So it literally says 'no muscle feeding', which helps explain why it describes conditions where muscles waste away.
