IPA: /ˈsaɪəˌlɪzəm/
KK: /ˈsaɪəˌlɪzəm/
A show of knowledge that is shallow or superficial, often intended to impress others rather than to demonstrate true understanding.
His sciolism was evident when he tried to discuss complex topics without really knowing the details.
Sciolism is derived from "sciolus" (meaning a superficial or pretender) in Latin, which is a diminutive form of "sciens" (meaning knowing). The suffix "-ism" (meaning a practice or philosophy) indicates a belief or practice. Thus, sciolism refers to a superficial knowledge or a pretense of knowledge.
Think of someone who pretends to be 'knowing' ('sciens') but only has a 'superficial' understanding — that's what sciolism means.
