Etymology
The word deflector is a modern English formation built from classical Latin components. It is derived from the Latin verb deflectere, meaning "to bend or turn aside," which itself is a compound of the prefix de- ("away from") and flectere ("to bend"). The suffix -or, also from Latin, is added to form an agent noun, denoting an object that performs the action of the verb. Thus, the literal meaning of "a thing that bends something away" evolved logically into its modern technical sense of a device that redirects the path of a moving substance or object, such as a wind deflector or a particle deflector on a spacecraft.
