Usage Rules
Three rules: Accuracy — exact codeword, no shortcuts. Brevity — under 30 seconds. Clarity — enunciate each syllable.

Decimal = "DECIMAL" · Period = "STOP" · Never say "REPEAT" — say "SAY AGAIN"
History
ICAO tested each word against noise, interference, and 31 language groups. Alfa (not Alpha) — prevents Spanish/Portuguese mispronunciation. Juliett (double-T) — forces French speakers to pronounce the final consonant. Niner (not Nine) — avoids confusion with German "nein" (no).
