postal
UK: ˈpəʊstl | US: ˈpoʊstl
adj. relating to the mail system or post office
adj. designating services or fees associated with mail delivery
The word postal emerged in the early 19th century, derived from post (itself rooted in the Latin postis, which evolved to mean "mail system" through French). The suffix -al was added to create an adjective describing anything related to mail services. The shift from "doorpost" to "mail" reflects the historical use of fixed stations (like posts) for relaying messages.
