Etymology
The word 'deficiency' originates from the Latin verb deficere, meaning "to fail, to be wanting, to desert." This verb itself is a compound of the prefix de- ("away from, down") and the verb facere ("to make, to do"). The literal sense is thus "to make away from" or "to do incompletely," implying a falling short. Over time, the abstract noun deficientia was formed to describe the state or condition of this lack or failure. Entering English in the 16th century, 'deficiency' retained this core concept of an insufficiency or absence of something necessary, whether material or abstract.
