Malayalam is both agglutinative and inflective language . it belong dravidian language category . In apertium we are trying to implement englaish malayalam pair using hfst .it is described here Starting_a_new_language_with_HFST

Morphotactic using lexc

let's take an example of a noun word , malayalam noun can have 8 inflections , nominative,dative, instrumental, locative ,accusative,vocative and sociative . it can be also classified on the basis on number ,singular and plural , let's declare essential symbols

Multichar_Symbols

%<n%>           ! Noun                        ! നാമം

%<nom%>         ! Nominative                  !

%<acc%>         ! Accusative                  !

%<dat%>         ! Dative                      !

%<soc%>         ! Sociative                   !

%<gen%>         ! Genitive                    !

%<ins%>         ! Instrumental                !

%<loc%>         ! Locative                    !

%<voc%>         ! Vocative                    !
