Morphology

hypotonia = hypo + ton + ia

Although hypo- and -ia are recognizable classical elements, the bound root ton- is specialized medical morphology, so the meaning is not readily recoverable for an average learner.

Etymology

Hypotonia comes from Greek parts: hypo- meaning 'under' or 'low' and tonia, related to tone meaning 'tension' or 'tightness'. So, hypotonia means 'low muscle tone', which is why muscles can feel soft and floppy.
