Morphology

hypoplasia = hypo + plas + ia

The meaning is compositionally clear from hypo- 'under, deficient' plus the medical formation root plas and noun-forming -ia, but these are specialized medical elements rather than everyday English words.

Etymology

Hypoplasia comes from hypo- 'under' and -plasia 'formation' or 'growth', a root you also see in plastic 'formed'. So hypoplasia means a body part has 'under-formation' — it did not grow enough and has fewer cells than normal.
