means The state of not knowing something — lacking the knowledge, information, or awareness that a situation calls for.

from From Latin 'ignorantia,' built on 'ignorare' — 'to not know, to take no notice of.' That verb pairs the negative prefix 'in-' (here softened to 'i-') with a root tied to 'gnoscere,' 'to know' — the same ancient know-root that surfaces in 'cognition,' 'notice,' and even Greek 'gnosis.' It strolled into English through Old French 'ignorance' in the Middle Ages, carrying its blank stare intact.
