What is cagey? How to use in English

The word "cagey" is believed to have originated in the mid-20th century in the United States. It is likely a combination of "cage," meaning a confined or restricted space, and the suffix "-y," which is often used to form adjectives. One possible etymology of the word "cagey" is that it came from the phrase "cagey about," which was used to describe someone who was secretive or evasive. Over time, the phrase may have been shortened to simply "cagey," with the meaning shifting to describe someone who is cautious, suspicious, or evasive in their words or actions. The word "cagey" gained popularity in the 1960s and 1970s, particularly in the context of politics and espionage. It is now commonly used in a variety of contexts to describe someone who is secretive, uncooperative, or difficult to read.
