What Are Possessive Adjectives?

Possessive adjectives are small words. They tell us about ownership or connection. They answer the question: Whose?

• They always come before a noun.
• They do not change their form, no matter if the noun is singular or plural.

How Do We Use Possessive Adjectives?

We use possessive adjectives to show that something belongs to someone or something. They describe the noun that follows.

• For example, This is my car. (The car belongs to me.)
• Another example: She likes her new bag. (The bag belongs to her.)

スペイン語話者がよく犯す間違い

Spanish speakers often make these mistakes:

• Using subject pronouns instead of possessive adjectives: In Spanish, you might say "Yo libro" (incorrect) or "mi libro." In English, always use the possessive adjective: I have my book. (NOT I have I book.)
• Confusing his, her, its, 、および their with "su": In Spanish, "su" can mean his, her, its, 、または their. In English, you must choose the correct one based on who owns the item. For example, He has his car. (NOT He has her car. if it's his car).
• Confusing its そして it's: Its is a possessive adjective. It shows possession (e.g., The dog wagged its tail.). It's is a contraction of it is または it has （例：, It's a beautiful day.).

My is a possessive adjective. It comes before a noun (e.g., my book). Mine is a possessive pronoun. It replaces the noun (e.g., That book is mine.).

Do possessive adjectives change for plural nouns?

No, possessive adjectives do not change. For example, you say my car (singular) and my cars (plural). The word my stays the same.
