sciolism (noun) -
: a superficial show of learning
Source : Merriam-Webster
Etymology : Sciolism comes from the Late Latin sciolus, which means "smatterer" (or "one who speaks with spotty or superficial knowledge"). "Sciolus" comes from the diminutive of Latin scius, meaning "knowing," which itself comes from the verb scire, meaning "to know." Of course, if you know something about Latin roots, you know that "scire" is the source of many other English words, including "science," "prescience" ("foreknowledge"), "nescience" ("lack of knowledge"), and "conscience." A relatively new word, first used in 1816.
