Linguistic Origin & Historical Etymology

Derived from the Late Latin word 'rectrix', meaning a female ruler or guide (feminine of rector, ruler), which was adopted in ornithological Latin as a new taxonomic term. It entered scientific English in the 19th century based on the root 'rector' (to guide or steer), metaphorically describing these tail feathers as the steering mechanism of a bird in flight.
