Adjectives before nouns

An adjective before a noun describes the thing or helps identify which one is meant. In the old red engine, old and red both depend on engine. This job before the noun is called premodifier.

Does the same job make the same kind of word?

Kitchen is a noun premodifier of clock; it fills the same function slot as an adjective.

The two diagrams separate the kind of word from the job it does. Old is an adjective and kitchen is a noun, but both premodify the following noun. Position can reveal the job before it reveals the word class.

Work from the noun outward

  1. Find the noun head in the noun phrase.
  2. Mark each earlier dependent that narrows that noun as a premodifier.
  3. Use the word’s other patterns and its meaning to decide whether it is an adjective, a noun, or another form.

A common adjective can often also follow a linking verb or take a comparative form, but neither pattern defines every adjective. The premodifier function does not identify the word class by itself.

a restricted case

Sometimes the adjective also supplies the head

In this course’s analysis of the poor, poor is the nominal head and is fused with the premodifier function.

Here poor still has adjective form, but no noun is expressed, so the model records both jobs on one word. The poor has an established collective meaning. Other combinations of the and an adjective do not automatically refer to a group of people.
