The question is the word was a linking verb is a common point of confusion for students learning English grammar, because was can serve more than one grammatical role depending on the sentence context. Understanding when was functions as a linking verb—and when it does not—helps learners avoid errors in subject‑verb agreement, tense usage, and sentence construction. This article explores the nature of linking verbs, examines the various uses of was, provides clear examples, and offers practical tips for identifying its function in any sentence.
What Is a Linking Verb?
A linking verb (also called a copula) does not express an action; instead, it connects the subject of a sentence to a subject complement that describes or renames it. The most typical linking verbs are the different forms of the verb to be: am, is, are, was, were, be, being, been. Other verbs such as seem, become, appear, feel, look, sound, and taste can also act as linking verbs when they link the subject to an adjective or noun phrase that describes a state or quality.
Key characteristics of a linking verb:
- It shows a state of being or condition, not an action.
- It is followed by a subject complement (either a noun/adjective that renames or describes the subject).
- It can often be replaced by another form of be without changing the core meaning of the sentence.
The Verb “Was”: Forms and Functions
Was is the past tense singular form of the verb to be. Depending on its use, was can appear in three distinct grammatical capacities:
- Linking verb (copula) – connects subject to a complement.
- Auxiliary (helping) verb – combines with a past participle to form the passive voice or past progressive tense.
- Main verb expressing existence – in rare cases, was can stand alone to indicate that something existed in the past (though this usage still behaves like a linking verb because it links the subject to an implied state of being).
Recognizing which role was plays requires looking at the words that follow it and the overall meaning of the sentence.
When “Was” Acts as a Linking Verb
Was functions as a linking verb when it is followed by a noun, pronoun, or adjective that renames or describes the subject. In these cases, the sentence can be rephrased using another form of be (e.g., is, were) without altering the essential meaning Took long enough..
Examples of “Was” as a Linking Verb
| Sentence | Subject | Linking Verb (was) | Subject Complement | Explanation |
|---|---|---|---|---|
| **The sky was blue.And ** | The sky | was | blue (adjective) | Describes the state of the sky. Now, |
| **She was a teacher. Think about it: ** | She | was | a teacher (noun phrase) | Renames the subject. So |
| **The cake smelled delicious. So naturally, ** | The cake | smelled (linking verb) | delicious (adjective) | Smelled works like was here; was could replace it: *The cake was delicious. Think about it: * |
| **The results were surprising. ** | The results | were | surprising (adjective) | Plural past of be linking subject to adjective. |
In each example, removing the complement leaves a grammatically incomplete thought (The sky was.), indicating that was is linking the subject to essential information.
How to Test for a Linking Verb
A quick diagnostic is to substitute was with another form of be (e.g., is, were) and see if the sentence still makes sense:
- The sky is blue. → Still describes a state → linking.
- She is a teacher. → Still renames the subject → linking.
- The cake is delicious. → Still describes a quality → linking.
If the substitution preserves meaning, was is acting as a linking verb.
When “Was” Is Not a Linking Verb
Although was frequently serves as a linking verb, it also appears as an auxiliary verb in progressive and passive constructions. In these cases, was does not link the subject to a complement; instead, it helps form a verb phrase that expresses an action or a state resulting from an action Small thing, real impact..
Not the most exciting part, but easily the most useful.
1. Past Progressive (Continuous) Tense
Structure: was/were + present participle (-ing form).
- She was running when the phone rang.
- The children were playing in the yard.
Here, was combines with running to show an ongoing action in the past. The subject complement is absent; the meaning hinges on the action expressed by the present participle.
2. Passive Voice
Structure: was/were + past participle.
- The letter was written by John.
- The windows were cleaned yesterday.
In passive constructions, was helps shift focus from the doer of the action to the receiver. The past participle (written, cleaned) carries the main lexical meaning, while was merely marks tense and voice.
3. Existential “There Was” Sentences
Sentences beginning with there use was to indicate existence, but grammatically they still behave like linking verbs because the true subject follows the verb It's one of those things that adds up..
- There was a cat on the roof.
(True subject: a cat; was links it to the location on the roof.)
Even though the word order is inverted, the function remains copular: was connects the existential subject to a locative complement.
