What does cognizant mean? To be cognizant of something is to be aware of it or have knowledge of it. Such awareness can be called cognizance. Cognizant is almost always followed by the word of and the thing that the person is cognizant of, as in He was cognizant of the report at the time. It’s often used in the phrase cognizant of the fact, as in I’m cognizant of the fact that you dislike me, but we still need to work together to get this done. Cognizant is typically used in a formal way. The adjective aware means much the same thing but is used more broadly. Example: At what point did you become cognizant of the fact that you were not receiving everything that you were promised?

Explanation
If you are cognizant of what's going on at the table behind you in the lunchroom, that means you know they're plotting to throw peas at your head. If you are cognizant of something, you are aware of or informed about it. This 19th century adjective derives from Latin cognōscere, "to learn." For the English adjective and noun, an older pronunciation with a silent g was in use in legal contexts up until the early 20th century. In law, these terms refer to jurisdiction, or the right of a court to hear a case.
