Mygurudu

Mygurudu is a Malayalam-based secret language developed in Northern Kerala during the Malabar Rebellion of 1921.^[1][2] Prisoners used this coded language to pass messages without getting leaked.

Concepts

The fundamental idea behind Mygurudu involves the swapping of Malayalam alphabets. For example, Mygurudu uses ‘Ra’ instead of ‘Cha’, and ‘Pa’ instead of ‘Na’.

Current State

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. The Speech Science Research Forum of the Department of Linguistics of Kerala University has digitized and documented the structure of Mygurudu and other dying languages.^[2]
