Morphology

protoplasm = plasm (opaque) = proto + plasm

Although the word is historically built from proto- + plasm, its modern biological meaning is specialized and not directly predictable for most learners.

Etymology

The word protoplasm comes from Greek parts proto- meaning 'first' and plasma meaning 'a formed thing' or 'shaped substance'. So it was used to name the 'first formed' living material, which is why today protoplasm means the living substance inside a cell.
