Etymology

Origin of portcullis

1300–50; Middle English portecolys < Middle French porte coleice, equivalent to porte port 4 + coleice, feminine of coleis flowing, sliding < Vulgar Latin *cōlātīcius; see coulee, -itious

Explanation

A portcullis is a heavy castle door or gate made of metal strips that form a grid. A castle guardian might lower the portcullis to protect the people inside from an invading army. It was common during medieval times for castles to be protected by a portcullis or two. They could be raised and lowered as needed, sometimes in such a way that an enemy would be trapped between a first portcullis and a second. Today, you can still see a portcullis if you visit the Tower of London. The Old French root is porte coleice, "sliding gate," which combines coleice, "sliding or flowing," and porte, "gate or door."
