Etymology

Protoctist comes from the Greek parts proto- meaning 'first' and -ctist meaning 'created', so it originally meant 'first created'. Think of proto- like in prototype or protozoa, and that is why protoctist refers to simple, often single-celled organisms that are like the early forms of life.
