13. After writing your lexicon grammar, create a separate rule file called monishrul.regex that describes the alternations required for Monish. Compile it, and save the result as monish-rul.fst. Alternatively, if you wrote the lexicon in a script, simply expand the script to define the rules as well. The trick is to write rules that realize each underspecified vowel as front or back depending on the frontness or backness of the vowels of the root.

14. Compose the rule network under the lexicon network, and save the result as monish.fst, i.e. perform the following by hand or add the commands to your script file.7

xfst[0]: clear stack

xfst[0]: read regex @"monish-lex.fst" .o.

@"monish-rul.fst" ;

xfst[1]: save stack monish.fst
