What does cognizance mean?
Cognizance is a formal noun meaning awareness, knowledge, or conscious notice of something. When someone takes cognizance of a fact, they acknowledge it and factor it into their thinking — the phrase 'take cognizance of' is its most common modern habitat, appearing frequently in legal, governmental, and academic prose. A second, more specialized sense belongs to law: cognizance can denote the range of matters over which a court or authority has jurisdiction, as in matters falling within a tribunal's cognizance. The word derives from Latin roots via Old French and is related to cognition and recognize, all built on the Latin verb cognoscere, 'to come to know.' Though precise and dignified, cognizance is relatively rare in everyday speech, where speakers prefer plainer words like awareness or knowledge; it is best reserved for contexts where formality and exactness are valued.

Etymology of cognizance
Cognizance comes from Anglo-Norman and Old French conoissance/cognisance, ultimately from Latin cognoscere, meaning 'to get to know,' formed from com- ('together') and gnoscere ('to know'). It entered Middle English in the medieval period, where it also denoted a heraldic emblem by which followers recognized their lord. Its relatives include cognition, recognition, and incognito, all tracing back to the same Latin root.
How cognizance is actually used
Formal and somewhat elevated in register; rarely used in casual speech. In everyday English, 'awareness' or 'knowledge' is more common. The legal sense survives chiefly in technical contexts.
