Predicate Nominatives
Sometimes the subject is linked to a noun (person, place, thing, or idea) or pronoun (word replacing a noun such as he, she, they). This noun or pronoun that renames the subject is called a predicate nominative.
Miranda is a scuba diver.
The linking verb ''is'' connects the subject ''Miranda'' with the noun ''diver.'' It renames the noun, Miranda.
Predicate Adjectives
Sometimes the subject is linked to an adjective (word that describes a noun or pronoun) that describes it. This adjective is called a predicate adjective.
My notebook is full.
The linking verb ''is'' connects the subject ''notebook'' with the adjective ''full.'' It describes the noun, notebook.
The most commonly used linking verbs are forms of the verb be as can be seen in the chart.
Recognizing Linking Verbs
You may be starting to think that linking verbs are boring. After all, we've only seen sample sentences with the verb ''is.'' Don't worry. There are actually many linking verbs. Look at the illustration.
Now, you may notice that some of those words (taste, grow, smell, to name a few) look like action verbs, and you would be right. Depending upon how they are used in the sentence, these verbs can be action verbs or linking verbs.
But, don't worry, here is the key: If a verb is being used as a linking verb, you can replace it with the word ''equals'' and the sentence will have the same basic meaning.
The ballerina looked exhausted.
The ballerina = exhausted. The meaning stays the same. Looked is a linking verb.
That milk smells sour.
That milk = sour. The meaning stays the same. Smells is a linking verb.
Sometimes you try the ''equals'' test and the sentence's meaning is changed.
Tommy smells the flower.
Tommy = the flower. The meaning is changed. Smells is an action verb.
The ballerina looked out the window.
The ballerina = out the window. The meaning is changed. Looked is an action verb.
