Etymology
The term "Cambrian" originates from the Latin Cambria, the Roman name for Wales. This geographical label was adopted into geological terminology in the 19th century by Adam Sedgwick, who studied rock sequences in Wales to define this period. The suffix "-ian," meaning "pertaining to," was attached to form the adjective. Thus, the word's literal meaning, "of or relating to Wales," was abstracted to designate the geological period first identified and described from the rock formations found in that region.
