History and etymology of defective

The adjective 'defective' traces its origins to Latin. It is derived from the Latin word 'defectivus,' which comes from the verb 'deficere.' 'Deficere' consists of 'de,' meaning 'down from' or 'away from,' and 'facere,' meaning 'to do' or 'to make.' Thus, the etymology of 'defective' conveys the idea of something that has deviated or fallen away from its intended or proper state. Over time, this Latin term evolved into the English word 'defective,' which is used to describe something as flawed, damaged, or not functioning correctly due to faults or imperfections, reflecting its historical connection to the concept of things going astray or not living up to their intended standards.
