SCIOLIST, one who, with only a superficial knowledge or a smattering of knowledge on any particular subject, claims or pretends to a complete or profound learning. The Lat. sciohis, a diminutive of scius , learned, from scire, to know, is only found in post-classical times, e.g. Hieronymus, A.D. 420, Episl. 48. 18. It first appears in English at the beginning of the 17th century.
