Linking Verbs

There are two main rules for the usage of Linking Verbs

1. Linking verb + complement

A complement is an adjective phrase or a noun phrase. A complement relates to the subject: it describes the subject or identifies it (says who or what it is). Between the subject and complement is a linking verb, e.g. be.  

• The hotel was quiet. 
• The thief seemed depressed. 
• The book has become a best-seller. 
• It's getting dark.
• A week in the Lake District would make a nice break.

These are the most common verbs in this pattern.
+ adjective or noun phrase: appear, be, become, look, prove, remain, seem,
sound, stay
+ adjective: feel, get, go, grow, smell, taste, turn
+ noun phrase: make
There are also some idiomatic expressions which are a linking verb + complement,
e.g. burn low, come good, come true, fall asleep, fall ill, fall silent, ring true, run dry,
run wild, wear thin.

We can use some linking verbs in other patterns.
Linking: Your garden looks nice.
Intransitive: We looked at the exhibition.
 

NOTE
a. After seem, appear, look and sound, we use to be when the complement is a noun phrase
identifying the subject.

The woman seemed to be Lord Melbury's secretary.
NOT The woman seemed Lord Melbury's secretary.
But we can leave out to be when the noun phrase gives other kinds of information.
The woman seemed (to be) a real expert. 

b. There is a special pattern where a complement occurs with an action verb, not
a linking verb.

We arrived exhausted.
He walked away a free man.
I came home really tired one evening.
We use this pattern in a very small number of contexts. We can express the same meaning
in two clauses: We were exhausted when we arrived. 

2. Linking verb + adverbial

An adverbial can be an adverb phrase, prepositional phrase or noun phrase. An adverbial after a linking verb relates to the subject. It often expresses place or time, but it can have other meanings.
The coat was here. 

The conference is every year.
The drawings lay on the table. 

I'm on a diet.
Joan Collins lives in style. 

The parcel went by air.
Linking verbs with adverbials are be, go, lie, live, sit, stand and stay
