"Hang" refers to the act of suspending something from a higher point, allowing it to dangle freely. This can apply to various objects, such as clothes, artwork, or decorations. For example, people often hang pictures on walls to enhance their living spaces. In a different context, "hang" can also refer to a social activity where friends gather and spend time together, often informally. This usage is common among younger generations, who might say they are going to "hang out" with friends at a café or park.
