Background / Comments
I have known several people who thought they knew something, but were wrong. However, I’ve only run across one person who exhibited our word: he had read some manuals and learned some terms, but he had no understanding of the system whatsoever. His use of terms impressed supervisors because it sounded good, but to those who created the system, what he said was clearly nonsense. Our word came from the Latin Latin word sciolus (smatterer), which is a diminutive of the Latin word scius (knowing), which came from the Latin verb scire (to know).
