Cnossos is a proper noun (the legendary ancient city, also spelled Knossos). It denotes the Minoan palace complex on Crete and is used in archaeology, art history, and tourism contexts. The term is typically rendered with a final -s, and in English pronunciations the stress lands on the first syllable, yielding a two-to-three syllable pronunciation that leans toward a soft 'n' onset and a backward vowel quality in the second syllable.
