What is the term used for the letter 'X' in the phonetic alphabet?

The correct term for the letter 'X' in the phonetic alphabet is "X-ray." The phonetic alphabet is utilized in various communication contexts, particularly in aviation and military settings, to clearly convey letters and avoid misunderstandings that can arise from similar-sounding letters. "X-ray" is widely recognized and serves this purpose effectively.

Other terms may sound similar or be related to the letter 'X', but they do not serve the same function as "X-ray." For example, "Xerox" refers to a brand associated with photocopying and does not represent a specific phonetic designation. "Xenon" is a chemical element and has no connection to the phonetic alphabet. "Xenophobia" describes a fear or prejudice against people from other countries, which is unrelated to the phonetic usage. Therefore, "X-ray" stands out as the correct term within the context of the phonetic alphabet.
