The term "Royale" has multiple meanings and usages depending on its context.
In French, it is an adjective that means 'royal' or 'regal', implying something of high quality or status. For example, when referring to a hotel, restaurant, or other establishment, the word Royale implies luxury, elegance, and sophistication. In this context, using "Royale" in the name of an establishment is meant to convey a sense of exclusivity and prestige.
In English, it can also be used as a noun to describe a type of cigarette that was popular during the early 20th century. These cigarettes were longer than usual and marketed as being more elegant or sophisticated. The term "Royale" is still sometimes used today in reference to long, slim cigarettes.
In other contexts, such as referring to a type of coffee or beer, the word Royale can simply mean 'large' or 'extra-large'. For example, a cup of coffee that is larger than usual might be referred to as a "Royale".
