What is the phonetic alphabet word for the letter H?

The correct phonetic alphabet word for the letter H is "Hotel." The phonetic alphabet is developed to ensure clear and effective communication, particularly in situations where letters might be misheard or misunderstood, such as over radio transmissions. Each letter in the alphabet is associated with a specific word to provide clarity. "Hotel" is standardized in the NATO phonetic alphabet, which is used internationally by military and aviation professionals.

Other choices like "Hawaii," "Harmony," and "Hermes" are not part of the standardized phonetic alphabet and do not serve the purpose of clarity in communication as effectively. Using "Hotel" ensures that anyone familiar with the phonetic alphabet can accurately interpret the letter being conveyed, thus minimizing confusion in critical scenarios.
