the word "unswerving" is a modern english formation built upon the old english verb "swerve," which itself traces back to the proto-germanic root swerbaną, meaning "to wipe, sweep, or turn." the core concept of turning aside is preserved in the modern verb. the addition of the old english negative prefix "un-" creates the meaning "not turning aside." the "-ing" suffix, also from old english, transforms the verbal action into a descriptive adjective, characterizing a person or quality as constant and resolute. thus, the literal meaning of "not turning aside" evolved into the modern abstract senses of steadfast loyalty, unwavering determination, and undeviating constancy.
