the word 'tuxedoed' is a modern english formation, directly derived from the noun 'tuxedo'. the noun itself originates from tuxedo park, a private country club and residential community in new york, where the dinner jacket was popularized in the late 19th century. the suffix '-ed', of old english origin, is a productive adjectival suffix used to indicate possession of a quality, here meaning 'clothed in' or 'equipped with'. therefore, 'tuxedoed' logically and literally describes someone who is attired in the formal wear associated with that location.

Structure: tuxedo + ed tuxedo (noun, from the name of a place, tuxedo park) + ed (suffix, of germanic origin, forming adjectives meaning 'having' or 'wearing')
