The word "riffle" has an interesting etymology. It originated in the late 18th century in America and is derived from the German word "riffeln", which means "to curl the hair". This German term was borrowed and used in the context of card playing. In card games, the act of riffle shuffling involves interweaving two halves of a deck of cards, creating a distinct sound and visual effect as the cards are smoothly mixed together. Over time, "riffle" started to be used more broadly to refer to a rapid or undulating movement, similar to the appearance of a deck of cards being shuffled. Today, "riffle" can also refer to small waves or ripples on the surface of water, further emphasizing the visual similarity to the shuffling of cards.
