insufficiency

Falling short somehow

Insufficiency is the state of not having enough of something needed.

A medical insufficiency means an organ isn't functioning adequately: cardiac insufficiency, adrenal insufficiency.

More broadly, it describes any shortfall or inadequacy: The project failed due to an insufficiency of funds.

The word carries a clinical or formal tone compared to simpler alternatives like shortage or lack.
