In Spanish, the word for ‘mine’ is mío when referring to masculine nouns and mía when referring to feminine nouns.
For example, if you want to say ‘my book,’ you would say ‘el libro es mío’ (the book is mine). If you were talking about a feminine noun, like ‘my car,’ you would say ‘el coche es mío’ (the car is mine).
It’s important to match the form of ‘mine’ with the gender of the noun it refers to. This is a common aspect of Spanish grammar, where adjectives and possessives must agree in gender and number with the nouns they modify.
