Nominative case

In grammar, the nominative case (abbreviated nom) is a special form that words can take. It tells us who or what is doing the action in a sentence. When we say "The cat is sleeping," the word "cat" is in the nominative case because it is the one sleeping.

The nominative case is also called the subjective case, straight case, or upright case. It is one of the grammatical cases that a noun or other parts of speech can have. This case marks the subject of a verb, meaning the person, place, or thing that is doing the action.

For example, in the sentence "The dog chased the ball," "dog" is in the nominative case because it is the one chasing. The nominative form of a word is often the one you will find listed first in dictionaries. This case is important because it helps us build clear and correct sentences in many languages, including English and Latin.

Etymology

The word "nominative" comes from a Latin phrase meaning "case for naming". This idea was also used in Ancient Greek. A writer named Dionysius Thrax called it "straight" to make it different from other cases.

Characteristics

In grammar, the nominative case is a way that words change to show they are the subject of a sentence — the word doing the action. For example, in English, we use pronouns like I, we, he, she, and they when they are the ones doing the action. The nominative case is often the form you’ll find in dictionaries.

Many languages, such as Albanian, Arabic, German, Latin, and Russian, use the nominative case. In English, the nominative case is sometimes called the subjective case, and it is used for subjects of verbs. Other forms, like me, us, him, her, and them, are called the objective case and are used for objects in sentences.

Examples

The nominative case shows who or what is doing something in a sentence. In sentences where something is happening, the nominative case is the person or thing doing the action. For example:

• The boy saw her.
• She was seen by the boy.

In sentences that describe someone or something, the nominative case is used for both the subject and the description. For example:

• Socrates was a wise man.
• Socrates was wise.
