40 Xcellent X-Words
When the lexicographer Dr. Samuel Johnson put together his Dictionary of the English Language in 1755, he included a disclaimer at the bottom of page 2308 that read, “X is a letter which though found in Saxon words, begins no word in the English language.” Noah Webster went one better when he published his Compendious Dictionary in 1806 that included a single X-word, xebec, defined as “a small three-masted vessel in the Mediterranean Sea.” Although, by the time he compiled his landmark American Dictionary in 1828, that total had risen to 13.

Xanthos was the Ancient Greek word for “yellow,” and as such is the root of a number of mainly scientific words referring to yellow-colored things.
