2.7 Attributes

Attributes are words that function the same way as adjectives, but usually they come in the first position, that is, before the noun. While regular adjectives are found in the predicate, attributes do not need a verb to link them to the noun they're modifying. Adjectives are not the only parts of seech that can serve as attributes. Participles, pronouns, partitives, and other nouns can function the same way. 

In this quote, Roger Sterling is giving us three examples of attributes. The first one is the avocado people, he's referring to the people who work in the avocado business.

 In the main sentence (see what i did there?), he's using the superlative biggest to modify the noun job. 

Roger's job in these meetings is to keep the clients from saying "golly" too many times. These is the demonstrative pronoun modifying the noun meetings. 

 Gene is Sally's little brother. The noun baby modifies the proper noun Gene.

Here, Don is using a possesive pronoun, Our, and another superlative, worst, to describe the noun fears.

Here, the quantifier Every, appears before the noun generation.
