Surface Forms

hyperplasia singular
hyperplasias plural

Morphology

hyperplasia = hyper + plasia

Although 'hyper-' is a recognizable prefix meaning excessive, the remaining combining form '-plasia' is technical and not a transparent standalone English base, so the full meaning is not easily predictable for a typical learner.

Etymology

Hyperplasia comes from two Greek parts: hyper- meaning 'over' (as in hyperactive) and -plasia meaning 'formation' (the same root in plastic, which is about forming). So hyperplasia literally means 'over-formation' and refers to an extra growth in the number of cells that makes a tissue larger.
