Explanation:
A noun is a word that names a thing, a place, or a person. In the sentences above, the nouns are: boy, house, wolf, forest, magician, people, girl, friend, man, and food. They are all common nouns, meaning that they do not refer to something or someone in particular.
An adjective is a word that modifies a noun by giving it a quality. For instance, when we say "magician", we only get to know about the profession of this person. But, when we add the adjective "sly", we know something more about him. We know he is deceitful, that is, someone who cannot be trusted.
