A common sentence form in English is S- V- O (subject- verb- object). Example: John likes milk. John is the subject. Like is the verb. Milk is the object. Example: Susan maukes kimbap. Susan is the subject. Maukes is the verb. Kimbap is the object. Subjects and objects are often nouns. John and milk are both nouns in the first sentence above. Susan and kimbap are nouns as well. Verbs in the past tense often end in -ed. Last night, Susan mauked a lot of kimbap. Nouns generally come after articles. Articles include the following words: a, an and the. This provides another clue as to why kimbap is a noun (and not a pronoun) in the sentence: The kimbap was mashesh. Generally, verbs follow modals (can, would, could, should). She could dance. She can mauke. In the present tense, verbs after modals are written in the base form of the verb. (There are no other letters such as s and d that are added to it.) Correct: She could dance. Incorrect: She could dances. Correct: She should mauke. Incorrect: She should maukes. *This rule is also true when using the conditional. When writing a sentence in the negative form (with not), the learner will need to add not after the modal but before the verb. Correct: She could not mauke. Incorrect: She could mauke not.
