Etymology
The word 'defection' originates from the Latin verb deficere, meaning "to desert, revolt, or fail," which is itself a compound of the prefix de- ("away from") and the verb facere ("to make, to do"). The literal sense of deficere was "to undo" or "to cease doing," implying a withdrawal of action or support. This evolved into the specific meaning of abandoning a duty, leader, or cause. Entering English in the 16th century via the Latin noun defectio, the term has retained its core logic of a "making away from" or a "falling away," capturing both the act of desertion and the state of failure or lack.
