limousine
A very long, fancy car usually driven by a hired driver.
A limousine is an exceptionally long, luxurious car, often driven by a professional chauffeur. You've probably seen one: they're so stretched out they look almost comical, sometimes long enough to fit ten or twelve people inside. The passenger compartment is separated from the driver by a partition, and inside you might find leather seats, a small refrigerator, fancy lighting, or even a television.
People rent limousines for special occasions like weddings, proms, or important business events.
Today, limousine can refer to any luxury vehicle service, even if the car isn't stretched. Airport limousine services might use regular luxury sedans or SUVs. The word suggests professional, high-end transportation rather than just the extremely long party cars you see in movies.
When something is described as limousinesque or limousine-like, it means extravagantly long, fancy, or over-the-top luxurious.
