Knowledge
Etymology
From Middle English "knowlechen" (to acknowledge, recognize), built on "know" (Old English "cnawan"). The old sense of acknowledgment lingers: to have knowledge of something is to have recognized and taken it in, not merely to have been exposed to it.
noun · /NOL-ij/
Justified true belief; awareness or understanding gained through experience, study, or reasoning.
What it names
The goal of all inquiry, marking the crucial gap between merely having information and genuinely knowing.
Example
The manual gave him information; only a year of mistakes turned it into knowledge.
Related idea
Knowledge is grasping what is true and why; wisdom is knowing what to do with it — one can possess vast knowledge and still lack the wisdom to apply it well, and the reverse can also hold.
