Which term aligns best with "prosperity" in the context of personal wealth?

The term that aligns best with "prosperity" in the context of personal wealth is "wealth." Prosperity refers to a state of flourishing or thriving, particularly in terms of financial or material resources. It denotes a condition where an individual has ample resources, financial security, and the ability to enjoy a certain quality of life. Wealth encapsulates these characteristics, representing the accumulation of valuable resources and financial assets.

In this context, penury refers to extreme poverty, which is directly opposite to prosperity. Possibility suggests potential or opportunity rather than the reality of having wealth. Deadliness is unrelated, as it pertains to fatality or danger rather than financial standing. Therefore, wealth is the term that most accurately captures the meaning of prosperity when discussing personal wealth.
