peppery

the word "peppery" is a straightforward english formation, combining the noun "pepper" with the productive adjectival suffix "-y". the noun "pepper" itself has a long journey, entering old english from latin and greek, which borrowed it from an indo-aryan source, reflecting the ancient spice trade. the suffix "-y" is a native germanic element used to indicate possession or resemblance. thus, "peppery" literally means "having the qualities of pepper," a logic which extended seamlessly from describing a sharp, pungent flavor to metaphorically characterizing a fiery, irritable temperament.
