Etymology
the word 'tuxedo' originates from tuxedo park, a wealthy enclave and country club in new york state. in the late 19th century, a tailless dinner jacket, inspired by british fashion, was introduced and popularized among the club's members. this distinctive garment became associated with the location, and its name was generalized to refer to the jacket and the entire formal suit. thus, a proper noun transformed into a common noun denoting a specific style of formal wear.
Analysis
the word is a toponym, borrowed directly from the name of a location. it is not productively formed from smaller, meaningful english morphemes.
