-- Trying to decide when to use the verbal affixes like meng-, ber-, -i etc.
-- I understand that this goes beyond mere syntax, so any rules are necessarily incomplete.
-- I want to find out what's a good API to use in applications, where you need finer control of when to use prefixes.

----------------------------------------
-- Simple declarative sentences

-- Intransitive verbs

Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (DetCN (DetQuant (PossPron i_Pron) NumSg) (UseN cat_N)) (UseV walk_V)))
LangEng: my cat walks
LangMay: kucing saya berjalan

-- As a verbal complement
Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (DetCN (DetQuant (PossPron i_Pron) NumSg) (UseN cat_N)) (ComplVV want_VV (UseV walk_V))))
LangEng: my cat wants to walk
LangMay: kucing saya mahu jalan

-- Transitive verbs

Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (ComplSlash (SlashV2a read_V2) (DetCN (DetQuant this_Quant NumSg) (UseN book_N)))))
LangEng: I read this book
LangMay: saya membaca buku ini

-- As a verbal complement
Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (ComplVV want_VV (ComplSlash (SlashV2a read_V2) (DetCN (DetQuant this_Quant NumSg) (UseN book_N))))))
LangEng: I want to read this book
LangMay: saya mahu baca buku ini

-- How about words like mengajar and belajar? Is the prefix more important here?

Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (AdvVP (ComplSlash (SlashV2a learn_V2) (MassNP (UseN science_N))) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))
LangEng: I learn science in the school
LangMay: saya belajar sains di sekolah

Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (AdvVP (ComplSlash (SlashV2a teach_V2) (MassNP (UseN science_N))) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))
LangEng: I teach science in the school
LangMay: saya mengajar sains di sekolah

-- The way the grammar is currently defined, we'd get the same output for both "I want to learn/study science". Is this correct, or should one or both of the verbs keep the ber/meng prefix in this context?
Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (AdvVP (ComplVV want_VV (ComplSlash (SlashV2a teach_V2) (MassNP (UseN science_N)))) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))
LangEng: I want to teach science in the school
LangMay: saya mahu ajar sains di sekolah

Lang: UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (UsePron i_Pron) (AdvVP (ComplVV want_VV (ComplSlash (SlashV2a learn_V2) (MassNP (UseN science_N)))) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))
LangEng: I want to learn science in the school
LangMay: saya mahu belajar sains di sekolah

-- How about interaction with passive? These sentences are very artificial, but imagine they made sense:
Lang: PhrUtt NoPConj (UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (DetCN (DetQuant this_Quant NumSg) (UseN book_N)) (AdvVP (PassV2 learn_V2) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))) NoVoc
LangEng: this book is learned in the school
LangMay: buku ini dibelajar di sekolah

Lang: PhrUtt NoPConj (UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP (DetCN (DetQuant this_Quant NumSg) (UseN book_N)) (AdvVP (PassV2 teach_V2) (PrepNP in_Prep (DetCN (DetQuant DefArt NumSg) (UseN school_N))))))) NoVoc
LangEng: this book is taught in the school
