The phrase "make aware" means to inform or enlighten someone about something. When you make someone aware, you are bringing something to their attention that they may not have known about. This could involve sharing information, raising consciousness about an issue, or simply letting someone know about a particular fact.
The word "aware" comes from the Old English "wær," meaning "cautious, watchful." The prefix "make" comes from the Old English "macian," meaning "to cause to be." When combined, they form the action of causing someone to recognize or understand something.
