玄 — twisted silk threads, top stroke 亠 over 幺
玄 originally depicted a small bundle of twisted, dyed silk threads, suggesting the deep reddish-black color of the dye. From this concrete sense it shifted to mean 'dark' or 'black,' then extended metaphorically to 'mysterious,' 'profound,' or 'abstruse,' as in Daoist philosophy.
