cloak
UK: kləʊk | US: kloʊk
n. a loose outer garment, typically sleeveless and reaching to the knees
vt. to conceal or disguise something
The word "cloak" traces back to Old French cloque or cloke, meaning "traveler's cape," derived from Medieval Latin clocca ("bell"), due to the garment's bell-like shape. The morpheme clo- reflects the idea of covering or draping, while -ak is a nominal suffix. Over time, the word evolved to denote both the physical garment and the metaphorical act of hiding or disguising.
