Noun cases indicate how a noun is used in a sentence, with variations between languages. English has five cases, including the genitive, subjective, objective, and dative. Other languages may have additional cases or spelling changes.
Noun cases refer to how a noun is used in a sentence, such as a subject, direct object, or possessive. While there is some case variation between languages, many languages use the same noun cases. These cases may be determined by placement in a sentence, a change in the spelling of the noun, or both.
There are five noun cases in English. With one exception, the genitive case, noun cases are determined by the noun’s position in a sentence. Punctuation, prepositions, and conjunctions can also provide clues as to the case of a specific noun. The simplest of these cases is the vocative, which is used only when a noun is distinguished from a phrase, as in “Jake, the laundry’s done” or just “Jake!” Votive nouns appear alone or are separated by a comma.
The genitive, or possessive, case is the only noun case in English that requires a spelling change. This case indicates ownership of something and is indicated by an apostrophe “s” for singular ownership or an apostrophe “s” for plural ownership. For example, “dog owner” means one dog, but “dog owner” means multiple dogs.
The subjective or nominative case is used when the noun is the subject of the sentence. Nominative nouns occur at the beginning of simple sentences and are close to the main verb. These names indicate what is performing the action. For example, in the simple sentence “The dog barked” and in the complex sentence “Running down the street, the dog barked”, the noun “dog” is the subject of both.
The objective or accusative case is used when the noun is the direct object of the sentence. Direct objects are nouns at which the action is taking place. For example, in the sentence “He drove his car,” the noun “car” is the direct object because the action of driving was performed on the car. Direct objects usually appear after the verb.
The dative case applies to indirect objects. Indirect objects are affected by the action of the sentence but are not what the verb acts on. For example, in the sentence “Jake gave Jill a piece of cake,” what Jake gave, the piece of cake, is the direct object and the person he gave the cake to, Jill, is the object. indirect.
Other languages may include spelling changes, usually at the end of the word, or may have additional cases or not. The Russian language, for example, includes a sixth case, the instrumental, which is used to indicate how something was done. For example, in the sentence “He colored the picture with crayons,” the word “crayons” would be in the instrumental case.
