Adjective (الصِّفة، النَعْت)

In Arabic, the adjective (الصِّفَة) is a word that describes something, like a person or place, and provides additional information.

The word المَوْصُوف refers to the noun that is being described by an adjective

Adjective-described Agreement Rule (الصِّفة и المَوْصُوف)

The adjective (الصِّفَة) fully agrees in state, gender, number, and definiteness with the described (المَوْصُوف)

This means that if the described noun is singular, the adjective must also be singular; and if the described noun is plural, the adjective must also be plural and so on.
