WWII Type One code that maps each English letter to one or more Navajo words.
During World War II the United States Marine Corps recruited
Navajo code talkers
to transmit messages in a code built on the Navajo language. The Type One code
spelled out words letter by letter, where each English letter was spoken as a
Navajo word whose English meaning begins with that letter (for example A is
"Wol-La-Chee", meaning Ant). Several letters had more than one approved word so
that repeated letters would not sound the same on the radio. This tool uses the
primary word for each letter when encoding, and accepts any of the known
variants when decoding.
