Which word is used in the phonetic alphabet for the letter 'X'?

The correct word used in the phonetic alphabet for the letter 'X' is "Xray." The phonetic alphabet, also known as the NATO phonetic alphabet, is designed to provide clear communication over radio or telephone transmissions by using distinct words for each letter of the alphabet. This is especially useful in military operations and other fields where clarity is critical.

"Xray" is specifically chosen for the letter 'X' to avoid confusion with similar-sounding letters. The other words listed do not correspond to 'X'—"Victor" represents 'V,' "Whiskey" represents 'W,' and "Uniform" represents 'U.' Each of these words serves its specific purpose in ensuring that communications can be accurately understood, reinforcing the importance of distinctiveness in phonetic representation.
