A different descendent of *skey yielded the Latin scandula, which later became scindula and was then borrowed into English, where it became shincle and then shingle (from the notion of splitting off a thin piece of wood). Back in English, *skey also yielded shed (meaning ‘to cast off’, as in shedding skin, but not the shed meaning a storage building). And *skey appears to be a variant of another root, *sek, meaning ‘to cut’, which gives us a whole host of other words like section and segment and saw, but I should probably cut this post off somewhere and save some things for another day.
