expend

This term carries a formal tone and is typically reserved for the consumption of finite resources like capital, energy, or time. It suggests a deliberate allocation of assets toward a specific goal, often implying a sense of depletion or a calculated cost associated with an achievement.

While similar to spend, it is rarely used for casual shopping or daily monetary transactions. Instead, it appears in technical, academic, or professional contexts to describe the systemic use of effort or resources, such as expending energy during an athletic event or expending funds on a corporate project.
