Root Breakdown

Root-derived
cognknow, recognize
+
-izantsuffix
=cognizant

Straight from Latin cognōscere ('to get to know') — the same source as quaint and acquaint, but via the undisguised Latin form. Cognizant means 'in a state of knowing,' i.e. aware. It is the formal twin of 'aware' and the clearest proof of the family's 'know' root.

Easily Confused

cognizant vs aware — same meaning, but cognizant is more formal and slightly heavier. Use 'aware' in everyday speech; reserve 'cognizant' for formal or written contexts ('the board is cognizant of investor concerns').
