Is Xi a word? Xi meaning


Xi actually has several definitions.

Perhaps most commonly, it's the 14th letter of the Greek alphabet. It's sort of a combination of "k" and "s." It's most similar to the English letters "c" or "x."

Xi is pronounced like "sigh" with a "z" sound at the beginning.

You will find the term commonly used in mathematics, physics and astronomy, usually as part of a formula or equation.

It's also a Roman numeral equivalent to eleven.

However, Scrabble tournaments allow the use of Xi because it is a word and not just a numeral. The word has been around since the 15th century, but people rarely use it today. The exception, of course, is Scrabble tournaments, where it gets a fair amount of play thanks to its high point value and low effort requirement.

Examples of Xi in a Sentence:

  • What the heck does "xi" mean?
  • I don't think "xi" is even a word.
  • Where's the dictionary? I'm challenging "xi."
