My first attempt to develop a . I was using and a word list based approach. It was not successful because of rich morphology of Malayalam. Even though I prepared a manually curated 150K words list, it was nowhere near to cover practically infinite words of Malayalam. For languages with productive morphological processes in compounding and derivation that are capable of generating dictionaries of infinite length, a morphology analysis and generation system is required.
Hunspell has a limited compounding support, but limited to two levels. Malayalam can have more than 2 level compounding and sometimes the agglutinated words is also inflected. Hunspell system has But it is very limited to support complex morphology like Malayalam. With the help of Nรฉmeth Lรกszlรณ, Hunspell developer, I had explored this path. But abandoned due to many limitation of Hunspell and lack of programmatic control of the morphological rules.
