Morphology

nucleoplasm = nucleus + plasm (semi-transparent) = nucleo + plasm

Built from the scientific combining forms nucleo- (nucleus) + plasm (formed substance); composition is clear to those with scientific knowledge but the morpheme 'plasm' is technical and may be unfamiliar to average learners.

Etymology

Nucleoplasm comes from two parts: nucleo-, from nucleus meaning 'center', and -plasm, the same root as plasma meaning 'substance' or 'fluid'. So nucleoplasm is the fluid substance inside the nucleus that holds and supports the chromosomes.
