Spelling the English alphabet on the phone or radio is sometimes hard to clearly exchange that alphabet to another party, especially by non-native speakers or people with different accents. This issue is also common in aviation and military so the ICAO (International Civil Aviation Organization) created the codeword representing a spelling to each alphabet for better communication and the NATO (North Atlantic Treaty Organization) has adopted this phonetic alphabet to be used in the military as well.

Here is the list of NATO Phonetic Alphabet from A to Z:
A – Alpha, B - Bravo, C – Charlie, D – Delta, E – Echo, F – Foxtrot, G – Golf, H – Hotel, I – India, J – Juliett, K – Kilo, L – Lima, M – Mike, N – November, O – Oscar, P – Papa, Q – Quebec, R – Romeo, S – Sierra, T – Tango, U – Uniform, V – Victor, W – Whiskey, X – X-ray, Y – Yankee, and Z – Zulu.

In order to use this in communication, you can spell each letter in the NATO Phonetic Alphabet format. For example, you want to communicate the word `beach`, you can say “beach as in Bravo-Echo-Alpha-Charlie-Hotel” or “beach… b as in Bravo, e as in Echo, a as in Alpha, c as in Charlie, and h as in Hotel”.
