The compound adjective 'Vegas-style' is a modern formation that directly references the city of Las Vegas. The city's name itself originates from Spanish, where 'vegas' means "meadows," describing the valley's grasslands when named in the 19th century. The word 'style' derives from Latin 'stilus', an instrument for writing, which evolved to denote a characteristic manner of expression or execution. The term 'Vegas-style' thus logically combines the geographical and cultural referent with the concept of a distinctive manner, encapsulating the specific, over-the-top aesthetic of entertainment, gambling, and nightlife that Las Vegas famously embodies, transforming the literal "meadows" into a symbol of manufactured extravagance.
