Both pronunciations emphasize the first syllable and have a silent "t" at the end, which is a common mistake to avoid; it's not pronounced "tarot-t."
The origin of the word "tarot" is somewhat uncertain. It is thought to be derived from the Italian word "tarocchi," used to describe the cards in Italy. The term "tarocchi" itself might have been derived from the Taro River in northern Italy or from an Arabic word, although these origins are speculative. The game was introduced into Europe via the Islamic world, where card playing was already a popular pastime. Over time, tarot cards evolved from their gaming function to their use in divination, reflecting broader trends in European culture towards the mystical and esoteric.
