In Spanish, “venti” is not a standard word, but it sounds similar to “veinte,” which means “twenty” (20).
However, in the context of coffee (like at Starbucks), “Venti” is used to refer to a size of drink, which is typically 20 ounces for cold drinks and 16 ounces for hot drinks, though it originates from the Italian word “venti,” meaning “twenty.”
