A fortune teller's deck of cards is known as a Tarot, which is a five-letter word. Tarot cards are used for divination and fortune telling, and have been around since the mid-15th century. They are typically composed of 78 cards, divided into two parts: the Major Arcana and the Minor Arcana. The Major Arcana consists of 22 cards that represent major life events, while the Minor Arcana consists of 56 cards that represent everyday life events. Tarot cards are used to gain insight into the past, present, and future, and can be used to help make decisions and gain clarity.
