Although I’ve observed elsewhere that there is potentially a gendered distinction between Shelley’s use of “form” (or synonymous) for men and women, here, he disrupts that binary in the creation of an androgynous being. The “s” sound throughout these lines recalls the readers attention back to its “sexlessness,” and, moreover, its period of “growth” and formation, at the moment as it is un-or-deformed, or “imaged forth.” The word “sex” itself engages in this non-linear, reflective pattern, the final “s” sound of the “x” recalling and reflecting the “s” at the beginning of the word.
