deficiency
Less than required
Deficiency is a lack or shortage of something needed.
A nutritional deficiency means the body isn't getting enough of a vitamin or mineral: iron deficiency, vitamin D deficiency.
The word implies falling short of a standard or requirement: a deficiency in the budget, cognitive deficiencies.
Unlike mere absence, deficiency suggests something should be present but isn't adequate.
