coil: [16] Ultimately, coil, cull, and collect are the same word. All come from Latin colligere ‘gather together’. Its past participial stem produced collect, but the infinitive form passed into Old French as coillir, culler, etc, and thence into English. In the case of coil, its original general sense ‘gather, collect’ (of which there is no trace in English) was specialized, no doubt originally in nautical use, to the gathering up of ropes into tidy shapes (concentric rings) for stowage.
