Genitive case facts for kids
The genitive case is a special way words change in grammar to show that something belongs to someone or something. Think of it like saying "whose?" or "of what?". It helps us understand who owns what. For example, in the sentence "the boy's bike was red," the bike belongs to the boy. The word "boy's" is in the genitive case. It shows possession.

What is the Genitive Case?
The genitive case is a grammatical case that shows a connection between two things. Most often, this connection is about possession. It tells you who owns something or to whom something belongs. It can also show where something comes from, or a relationship between people or ideas.
Showing Possession
The most common use of the genitive case is to show ownership.
- For example, "the dog's bone" means the bone belongs to the dog.
- "Sarah's book" means the book belongs to Sarah.
- The word in the genitive case (like "dog's" or "Sarah's") acts like an adjective, describing the noun that follows it.
Showing Relationships
The genitive case can also show other kinds of relationships, not just ownership.
- "The city's mayor" means the mayor of the city.
- "Today's news" means the news from today.
- "Children's toys" means toys for children.
In these examples, the genitive form connects the first word to the second, explaining its role or origin.
How We Use the Genitive in English
English uses a few main ways to show the genitive case. The most common are adding an apostrophe and 's (s) to a noun, or using the word "of."
The Apostrophe and 's (s)
For most singular nouns, we add s to show possession.
- Example: The cat's whiskers are long. (The whiskers belong to the cat.)
- Example: John's car is red. (The car belongs to John.)
If a singular noun already ends in 's', you can usually just add an apostrophe, or add s as well. Both are often correct.
- Example: James car is new. (The car belongs to James.)
- Example: James's car is new. (Also correct.)
For plural nouns that end in 's', we just add an apostrophe after the 's'.
- Example: The students' books are on the table. (The books belong to the students.)
- Example: The birds' nests are in the trees. (The nests belong to the birds.)
For plural nouns that do not end in 's' (like "children" or "men"), we add s.
- Example: The children's toys were scattered. (The toys belong to the children.)
- Example: The men's coats were hung up. (The coats belong to the men.)
Using "of"
Sometimes, especially with things that are not alive, we use the word "of" to show possession or relationship.
- Example: The roof of the house needs repair. (Instead of "the house's roof.")
- Example: The pages of the book are torn. (Instead of "the book's pages.")
Using "of" can make sentences clearer, especially when the possessor is a long phrase.
Possessive Pronouns
Pronouns also have genitive forms, which we call possessive pronouns or possessive adjectives. These words already show ownership without needing an apostrophe.
- Mine, yours, his, hers, its, ours, theirs are possessive pronouns.
- Example: That book is mine.
- My, your, his, her, its, our, their are possessive adjectives.
- Example: That is my book.
It's important not to confuse "its" (possessive) with "it's" (a contraction of "it is" or "it has").
Genitive Case in Other Languages
While English mostly uses s or "of," many other languages have more complex ways to show the genitive case. They might change the ending of the noun itself.
Latin and German
In languages like Latin and German, nouns change their endings depending on their case. The genitive case has specific endings.
- In German, "der Mann" (the man) becomes "des Mannes" (of the man, or the man's).
- In Latin, "rosa" (rose) becomes "rosae" (of the rose, or the rose's).
These endings help speakers understand the relationship between words, even if the word order is different from English.
Sumerian Example
The ancient Sumerian language also used a genitive case. On a seal of the Sumerian king Shulgi, the inscription "Lugal Kiengi Kiuri" means "King of Sumer and Akkad." The word for "king" has an ending that shows he is the king "of" Sumer and Akkad. This shows how old the concept of the genitive case is in human languages.
Why is the Genitive Case Important?
Understanding the genitive case helps us to:
- Be Clear: It makes it clear who owns what or what the relationship is between things.
- Understand Sentences: It helps us correctly interpret the meaning of sentences, especially in more complex writing or in other languages.
- Write Correctly: Knowing how to use s and "of" correctly is a key part of good English grammar.
