Spanish possessive adjectives and pronouns show ownership, such as my book, your backpack, or ours. This cheat sheet helps students choose the correct form based on who owns something and what is owned. It is useful because Spanish possessives must agree with the noun they describe or replace.
Students can use it as a quick reference when writing sentences, translating, or speaking.
Key Facts
- Short possessive adjectives come before the noun: mi, mis, tu, tus, su, sus, nuestro, nuestra, nuestros, nuestras, vuestro, vuestra, vuestros, vuestras.
- Short possessive adjectives agree in number with the thing owned, so mi libro means my book and mis libros means my books.
- Nuestro and vuestro forms agree in gender and number with the thing owned, as in nuestra casa, nuestros libros, and vuestras mochilas.
- Su and sus can mean his, her, its, your formal, or their, so the context or a phrase like de él or de ellos may be needed.
- Long-form possessive adjectives usually come after the noun: mío, tuyo, suyo, nuestro, vuestro, with forms that match gender and number.
- Possessive pronouns replace a noun and usually use a definite article: el mío, la tuya, los nuestros, las suyas.
- Use the form that matches the owned noun, not the owner, so la mochila de Juan is la suya because mochila is feminine singular.
- To avoid confusion with su, use de plus a person or pronoun, such as el libro de Ana or el libro de ella.

Common Mistakes to Avoid
- Matching the possessive to the owner instead of the thing owned is wrong because Spanish agreement depends on the noun being owned. Use nuestra casa because casa is feminine singular, even if the owners include males.
- Using su without context can be confusing because su can mean his, her, its, your formal, or their. Add de él, de ella, de usted, or de ellos when the owner is unclear.
- Forgetting plural agreement is wrong because possessives must match singular or plural nouns. Write mis lápices and tus libros, not mi lápices or tu libros.
- Using a possessive pronoun without the article is often incorrect in standard sentences. Say el mío or la tuya when replacing a noun, not just mío or tuya in most basic uses.
- Placing short possessive adjectives after the noun is wrong because forms like mi, tu, and su normally come before the noun. Say mi mochila, not mochila mi.
