Answer:
Every noun must be presented before the adjective and both must agree on number, gender and degree.
Explanation:
Although in English the nouns must be presented after the adjectives, in Spanish it must be presented in reverse and the noun must be written before the adjective so that the sentence is grammatically correct. In addition, the number, gender and degree of the noun and adjective must always be in agreement and be the same, which is also correct for sentences in English.
As you may already know, nouns are words that name any object, while adjectives are words that have characteristics of the noun.
Exemplos:
Todas son chicas hermosas. (They are all beautiful girls.)
Esta es una calle oscura. (This is a dark street.)
Esta es una canciĆ³n triste. (This is a sad song.)
