What does the term "void" most nearly signify?

The term "void" most nearly signifies "empty." In a general context, when something is referred to as void, it conveys the absence of content or substance. This is often used to describe a space that is clear or unoccupied, such as a void in a physical space or an emotional void. The other choices, while they represent certain states (full, solid, and overflowing), do not align with the core meaning of void, which fundamentally relates to emptiness or lack of anything present. Thus, the choice of "empty" aligns perfectly with the definition of the term.
