signage

The word 'signage' is a modern English formation, directly combining the familiar root 'sign' with the productive noun-forming suffix '-age'. The root 'sign' descends from Latin signum, meaning a mark, token, or signal, which itself may trace back to the Proto-Indo-European root sekw- meaning "to follow" or "to point out". The suffix '-age', entering English via Old French from Latin -aticum, commonly denotes a collective entity or the result of an action. Therefore, 'signage' logically builds from these components to mean "the collective result or assemblage of signs," a term that emerged in the 20th century to describe systems of signs, particularly for guidance or advertising.
