Why “metacognition” is a great word
The awareness and understanding of one's own thought processes. Formed within English from the combining form meta- (from Greek μετά, meaning 'beyond, higher, above') + cognition (from Latin cognitiō, meaning 'getting to know, knowledge'). Unlike 'cognition' (the raw act of knowing) or 'introspection' (a general survey of feelings), metacognition is the executive in the quiet office, monitoring the factory floor of the mind. It is the catch of doubt that makes you re-read a paragraph, the deliberate switch to a fresh tactic for a stubborn problem, and the sudden, clarifying knowledge of *why* you remembered a fact—the mind briefly stepping outside itself to observe its own machinery at work, a hall of mirrors with at least one mirror that sometimes works.
