portcullis

portcullis: [14] A portcullis is etymologically a ‘sliding door’. The word comes from Old French porte coleïce, a term made up of porte ‘door’ (source of English port, as in porthole) and coleïce ‘sliding’. This was a derivative of the verb couler ‘slide’, which came ultimately from Latin cōlum ‘sieve’ (source of English colander [14]).
=> colander, porch, port, portico
