The Letter “X”

X is usually pronounced as “zee,” but when it follows a vowel, it may be pronounced as “ks.” When it stands alone, it is pronounced “ex.” For example:

  • Xenic is pronounced “zenic.”
  • Lax is pronounced “lacks.”
  • X-ray is pronounced “ex-ray.”

X is often used in algebra to represent something that is unknown. Its use can be traced back to mathematician Rene Descartes. It is commonly used to represent something that is unknown, or generic. In advertising, identifying something as “Brand X” means that it is a generic product. For example, in a taste-test, a participant might be asked to compare Pepsi to “Brand X,”

In Roman Numerals, X means “ten.” This version of X is often used to make a more “trendy” or interesting name. “Generation X” is the tenth generation to be born after 1776. The “iPhone X” is the tenth version of the iPhone.

In recent years, X has been used in various ways to indicate more gender-inclusive terms. For example, “Mr.” can be converted to “Mx,” and “folks” can be converted to “folx.” Although this type of usage can be traced back to the 1990’s, it remains to be seen how widespread such uses have become. Oddly enough, in genetics, XX indicates a female chromosome, while XY indicates a male.

X is often used as an abbreviation for “extra.” For example, in clothing, “X-small” means “extra small,” and “X-large” means “extra large.”
