Mygurudu is aMalayalam-basedsecret language developed in Northern Kerala during theMalabar Rebellion of 1921.[1][2]Prisoners used this coded language to pass messages without getting leaked.
The fundamental idea behind Mygurudu involves the swapping of Malayalam alphabets.For example, Mygurudu uses ‘Ra’ instead of ‘Cha’, and ‘Pa’ instead of ‘Na’.
Mygurudu had about 400 speakers before 2020, however, the number of speakers has reached 900, and 2,500+ people are learning right now. This is mostly due to online platforms increasing accessibility to language learning resources.[1]The Speech Science Research Forum of the Department of Linguistics ofKerala University has digitized and documented the structure of Mygurudu and other dying languages.[2]
The following tables give the transposition scheme used in theMygurudu code.
