The word for ‘favorite’ in Spanish is ‘favorito’ for masculine nouns and ‘favorita’ for feminine nouns. For example, if you want to say ‘my favorite book,’ you would say ‘mi libro favorito.’ If you are referring to a feminine noun, like ‘my favorite movie,’ you would say ‘mi película favorita.’
It’s important to match the gender of the noun you are describing with the correct form of ‘favorito’ or ‘favorita.’ This is a common practice in Spanish, where adjectives must agree in gender and number with the nouns they modify.
