Why this word is great
POLYMATH — [Noun] A person of extraordinarily broad and comprehensive knowledge across many different fields of study. From Ancient Greek πολυμαθής (polumathḗs, "having learnt much"), from πολύς (polús, "much") + μανθάνω (manthánō, "to learn"). Unlike a specialist, who drills a single, deep well, or a dilettante, who skims a dozen shimmering surfaces, the polymath builds a connected continent of understanding. It is the ink-stained fingers tracing a botanical diagram, a musical score, and a philosophical proof on the same afternoon; the scent of ozone from an electrical experiment clinging to a volume of Persian poetry; the warmth of a library lamp illuminating texts on optics, fluxions, and sonnets long into the night—a quiet, lifelong rebellion against the fragmentation of the world, a testament to the unity of knowledge.
