Appropriations refer to a law passed by Congress allocating public or taxpayer funds to various government departments, agencies, and programs. The funds are designated for specific purposes and must be used in accordance with the conditions outlined in the appropriations legislation. This ensures that government spending is planned, controlled, and subject to oversight, allowing accountability in the use of public funds.

In the context of the National Institutes of Health (NIH), appropriations refer to the funds designated by Congress to support the NIH’s research initiatives, facilities, and operations. Appropriations are crucial for medical research and public health advancements.
