The concept of deferral in budget terminology refers to a temporary delay in budget authority, which aligns with the selected answer. This means that while the funds are still allocated and earmarked for specific purposes, the actual use or availability of those funds is postponed to a later time. This mechanism can be important for managing cash flow and ensuring that the funds are utilized effectively when they are needed.

In the context of budgetary practices, deferrals often occur due to factors such as changes in project timelines, shifts in revenue expectations, or strategic decisions to postpone expenditures in order to better align with financial realities. This temporary nature distinguishes deferral from other terms in budget language, as it does not signify a complete loss of the allocated funds or represent a fundamental change in project priorities.

Understanding deferral as a flexible management tool allows financial planners and budget professionals to navigate financial uncertainties while still holding onto the commitment of funds for future use.
