porch: [13] Porch and portico [17] are ultimately the same word. Both go back to Italian portico, a descendant of Latin porticus ‘covered gallery or entry’, but whereas portico was borrowed directly, porch came via Old French porche. Porticus was derived from Latin porta ‘gate’, source of the port of English porthole.
