The word for queen in Italian, which is regina (feminine, plural: regine), is easy to remember because it looks a lot like the verb to reign in English. Both words are related to the Latin term rex meaning king.

Regina is used to categorise fruit and grapes. The Regina dei Vigneti (lit. Queen of the Vineyards) is a type of premature grape of a golden colour. The Regina dei Frutteti (lit. Queen of the Orchards) is a type of peach tree that produces big and almost perfectly round fruit.
The noun regina is also the word for the most power chess piece on the board, as well as the queen in a deck of cards.
A word that often crops up in fairy tales and legends is the diminutive form reginetta (young queen). This also happens to be the name given to the winner of a beauty pageant.
The name Regina exists in Italian and English and has been in use since medieval times.
