What was uncanny about W?

W, or "Double U," is often considered uncanny due to its unique shape and sound. It visually resembles two overlapping "V" shapes, creating a sense of duality and complexity. This characteristic can evoke feelings of unease or intrigue, as it blurs the lines between unity and division. Additionally, its phonetic nature, being a letter that represents a sound identical to its shape, adds to its peculiarity in the context of language.
