Khmer Grammar Checker Rules
This is a list of Khmer grammar rules we have collected. It will be updated as we receive more. Submit rules to be added in the comments and/or corrections:
Rule #1: When something is numerated (like “ម្ហូបបីមុខ") make sure that the correct specifier is used for the noun. Create a list of classifiers and link them to their correct nouns (please add to this!): ក្បាល – copies of books, volumes, livestock ខ្នង - houses គូ - pairs of things គ្រាប់ - pellets, grains, tablets, bullets គ្រឿង - machinery ច្បាប់ - copies of pamphlets, newspapers, magazines ដើម – long, thin, stick like objects ដុំ - pieces and lumps តួ - letters of the alphabet, vehicle bodies, characters in a play. number + នាក់ - ordinary people ប្រអប់ - suits of clothing, sets of tools and equipment ផែន - disks ម៉ាត់ - words, utterances, mouthfuls រូប – pictures, shapes, forms, images, persons សន្លឹក – sheets of paper, leaves សម្រាប់ - suits of clothing, sets of tools and equipment អង្គ – monks, exalted people, images of Buddha
Rule #2: When the word “របស់" is used have some rules as to what follows (I think normally a pronoun, is this correct?)
Rule #3: Pronoun in a noun phrase may not follow a number unless it follows “របស់"
Rule #4: Normally adjectives come before a number (when the number is followed by a classifier it must precede the number)
Rule #5: Adjectives can go in any order (big yellow, yellow big)
Rule #6: Check the location of negators (មិន អត់ - for instance, do they have to precede a verb?)
Rule #7: Check the location of នេះ and នោះ (are there any rules for placement?)
Rule #8: Checkthe location of គាត់ (ex: when there is a pronoun and then a posessive "I" it normally is followed by គាត់ - ម្តាយខ្ញុំគាត់ស្លាប់ទៅយូរហើយ។)
Rule #9: Check location of ដែល - if there is a pronoun + ដែល + then normally it is followed by a verb សិស្ស ដែល ចេះ ខ្មែរមិនបាច់រៀនទៀត។
Rule #10: Check the location of spaces (Is there a way to know when to put a space? For example, is there always a space before ហើយនិង?)
Rule #11: When there is a មិន (or អត់) there is a ទេ before the ។
Rule #12: When there is a តើ there is a ទេ before the ។
Rule #13: When the phrase "ហើយឬនៅ" is written, it always needs a ? added at the end of the sentence
Rule #14: Detect question words in order to make sure a ? is added at the end of the phrase. List of Question words (please add to this!): អ្នកណា ឯណា កាលណា ពីអង្កាល ហេតុអ្វី យ៉ាងម៉េច ធ្វើអ្វី ម៉េចក៏
Rule #15: If អ្នកណា is used as the Subject, it should be followed by Verb and the sentence should be ended by ? អ្នកណា + Verb +...+ ?
Rule #16: If អ្នកណា is used as the object, it is always preceded by preposition preposition + អ្នកណា
Rule #17: ឯណា is always preceded by Verb, and the sentence should be ended by ? ( I am not sure for this rule, because I am not sure that: - ទុកនៅ is a Verb - or it is separated, ទុក is a Verb and នៅ is a preposition )
Rule #18: ហេតុអ្វី is followed by pronoun (subject) ហេតុអ្វី+ pronounce + verb
Rule #19: Possibly detect the usage of ចាន- a dish of food ដប- a bottle of water, wine, coke... កែវ- a glass of water, wine, juice...
Rule #20: How do you distinguish between the use of នឹង and និង?
និង = when it is between two clauses, two nouns, two sentences or two phrases (often there is a space before and/or after it)
នឹង = when it is after or before verbs, especially "will," and when it is after a preposition, especially, "with." (normally there is no space next to it)
Rule #21: ហើយនិង never ហើយនឹង
Rule #22: verb + ថា not ដែល
Rule #23: noun + ដែល not ថា
Rule #24: ចង់ + verb NOT ចង់បាន
Rule #25: ចង់បាន + noun NOT ចង់
Rule #26: ចេះ + verb not with a noun
Rule #27: ដឹងអំពីរបៀប + verb ok
Rule #28: ដឹង never with a verb (it is for information only)
Rule #29: ស្គាល់ never with a verb (only for person or place) maybe we could make a rule for លោក ពូ that would require ស្គាល់ rather than ដឹង
Rule #30: ដឹងថា can be used with a person or place (example: តើអ្នកមានដឹងថាលោកណាថានទៅលេងផ្ទះខ្នុំទេ?)
Rule #31: ចង់អោយ + subject + verb (exception: ចង់អោយ + direct object + indirect object)
Rule #32: ពី is a preposition and ពីរ is a number. So verb + ពី NEVER BEFORE A CLASSIFIER + noun or ណា or អី or អ្វី or ពី and possibly + phrase (with noun, subject, and verb ex. ពីផ្ទះខ្ញុំទៅសាលា។). (sometimes a verb +) ពីរ + classifier or noun + ពីរ
