Adjectives are words that describe nouns and pronouns, for example, pretty, happy, ugly, or smart. Adjectives usually come before the noun, as in, “That was a scary movie!”
Sometimes, adjectives follow a verb, like in the sentence, “Your baby is very cute.” But in this case, the adjective still modifies the subject of the sentence (your baby), not the verb (is). In Jessica’s example, the adjective tedious modifies the pronoun “it.”
Remember, unlike in some other languages, adjectives have only one form in English. They don’t have a singular and plural form or a masculine and feminine form. For instance, you wouldn’t say, “Those girls are beautifuls.” Even though there is more than one girl, you’d still say, “Those girls are beautiful.” Adjectives look the same no matter what noun they describe.
