Answer
Nastia Liukin's middle name, Valeryevna, is derived from her father's first name, Valeri. It's a patronymic naming tradition common in Russian culture, where the middle name is formed by adding "-ovich" or "-ovna" to the father's name. In Nastia's case, the feminine suffix "-ovna" is used since she's a female. This naming convention reflects the strong familial connection and honor bestowed upon children through their lineage.
