How to Say “Not Mine” in Spanish

no es mío
/no es mio/from spelling rules
The English phrase "not mine" is translated into Spanish as no es mío.
This phrase is used to state that something does not belong to the speaker. While no es mío is the standard way to express this, you might use the more formal No me pertenece (it does not belong to me) or the legalistic No es de mi propiedad (it is not my property) in official settings. In casual conversation, you might also say No es mío/a, es de otra persona to clarify that an item belongs to someone else.

Which one should you use?

There is a distinction between using the phrase as a possessive pronoun and a possessive adjective. Use no es mío to function as a possessive pronoun (meaning "it is not mine"). However, if you want to say "it is not my [noun]", you use the possessive adjective no es mi followed directly by the noun.

How does it change in a sentence?

The form of the phrase must change to match the gender and number of the noun it refers to. Use no es mío for masculine nouns and no es mía for feminine nouns. If you are discussing multiple objects, use no son míos for masculine plural objects and no son mías for feminine plural objects.

Did you know?

  • The word es is a cognate with the Sanskrit word अस्ति, showing a prehistoric connection between Spanish and ancient Indian languages.
  • While no me pertenece is a grammatically correct way to say 'it does not belong to me', using it in casual conversation can make you sound like a suspicious detective or a lawyer.
  • In Spanish, the gendered ending of mío or mía depends entirely on the object being discussed, not on whether the speaker is male or female.
