In the International Telecommunication Union phonetic alphabet, what is the code word for the letter D?

The International Telecommunication Union (ITU) phonetic alphabet is a standard set of words used to ensure clear voice communication over radio, particularly when signals are weak or noisy. In this standardized system, the letter 'D' is always represented by the word "Delta". Other options like "Denmark", "David", or "Dog" might be used in informal communication, police codes, or older alphabets, but they are not the internationally recognized ITU standard for amateur radio. Using non-standard words can cause confusion during international contacts.
