What phonetic alphabet word corresponds to the letter "O"?

The word that corresponds to the letter "O" in the phonetic alphabet is "Oscar." This phonetic alphabet is used primarily in military and aviation communications to ensure clarity and reduce misunderstandings when spelling out letters over radio or telephone transmissions. Each word in this alphabet is chosen for its distinctiveness, making it easily recognizable under various conditions, including poor sound quality or noisy environments.

"Oscar" is part of the NATO phonetic alphabet, which is widely adopted internationally. This system helps to reduce confusion since many letters can sound similar in verbal communication, especially, for instance, "O," "B," and "D." Other choices listed, such as "Olive," "Ocean," and "Owl," may not be recognized in standard phonetic practices and would not convey the same clarity that "Oscar" does in official communications.
