Linking verbs are one of the first grammar patterns ESL learners need to master because they connect the subject of a sentence to a description, identity, condition, or state rather than showing an action. In practical classroom work, I have seen students understand vocabulary quickly but still produce awkward sentences like “She feeling tired” or “They are in happy,” usually because the role of the linking verb is not yet clear. A linking verb, sometimes called a copular verb, joins the subject to a subject complement, which may be a noun, pronoun, or adjective. Common examples include be, seem, become, appear, feel, look, sound, remain, and stay. This matters because linking verbs appear constantly in introductions, opinions, descriptions, test responses, emails, and conversations. If you can say “The soup smells good,” “My teacher is patient,” and “He became an engineer,” you can handle essential English communication more accurately. This hub article explains the easy rules, the common mistakes, and the examples ESL learners need, while also pointing toward related grammar areas such as adjectives, predicate nouns, subject complements, and confusing verbs that can be either linking or action verbs.
What linking verbs do in a sentence
A linking verb does not express what the subject does. Instead, it tells us what the subject is, seems, becomes, or feels like. In “Maria is a doctor,” the verb is links Maria to the noun doctor. In “The sky looks gray,” looks links sky to the adjective gray. The information after the linking verb renames or describes the subject, so it is called a subject complement. This is the core rule ESL learners should remember: after a linking verb, use a word or phrase that identifies or describes the subject. In my editing sessions with learners, this single idea fixes many sentence errors.
The verb be is the most important linking verb in English, with forms such as am, is, are, was, were, be, being, and been. However, many other verbs can function as linking verbs when they describe a state. Seem suggests an impression: “The test seems difficult.” Become shows change: “The child became quiet.” Remain and stay express continuation: “The office remained closed,” “Please stay calm.” Sensory verbs such as look, sound, smell, taste, and feel often work as linking verbs too: “The plan sounds reasonable,” “The milk smells sour.”
Easy rules ESL learners can apply immediately
Rule one: after a linking verb, do not use an adverb when you need an adjective. Say “She looks happy,” not “She looks happily.” Happy describes she, so it must be an adjective. This is one of the most frequent mistakes I correct because learners know adverbs modify verbs, but linking verbs do not behave like ordinary action verbs here. Rule two: ask whether the verb shows an action or a state. In “He looked at the map,” looked is an action verb. In “He looked confused,” looked is a linking verb. The meaning changes the grammar.
Rule three: the word after the linking verb often answers “What is the subject?” or “What is the subject like?” In “My brother is an architect,” an architect identifies the subject. In “The room became noisy,” noisy describes the subject. Rule four: be careful with pronouns in formal English. Traditional grammar prefers “It is I” and “This is she,” because the complement refers back to the subject. In real conversation, native speakers often say “It’s me” and “This is her.” ESL learners should understand both, using the formal version for exams or highly formal writing and the common version for everyday speech.
Rule five: not every verb that comes before an adjective is automatically linking. Some verbs can be followed by object complements or different structures. For example, “They painted the door red” is not a linking verb pattern because painted is an action verb and door is the object. Knowing this distinction helps learners avoid overgeneralizing every adjective pattern.
Common linking verbs and how they differ
The most useful linking verbs can be grouped by meaning. The be verb states identity or condition. Seem and appear express impression, often with some uncertainty: “She seems ready,” “He appears nervous.” Become, get, turn, grow, and come can show change, though they are not always interchangeable. “The weather turned cold” sounds natural, but “The weather became cold” is more neutral and common in formal writing. “Get tired” is conversational, while “become tired” is more formal. Remain, stay, and keep can describe continuation: “The prices remain high,” “Stay focused,” “Keep calm” uses keep in a related result pattern.
Sensory linking verbs deserve special attention because they often confuse learners. “The cake tastes sweet” means the cake has a sweet flavor. “The chef tastes the cake” means the chef performs the action. “Your idea sounds interesting” describes the idea. “He sounded the alarm” is an action. “You look tired” describes appearance. “She looked at me” is an action. These contrasts matter in speaking tests and writing because they change both meaning and grammar.
| Verb | Linking Use | Action Use |
|---|---|---|
| look | The baby looks sleepy. | The baby looked at the toy. |
| feel | I feel sick. | I felt the fabric. |
| smell | The kitchen smells wonderful. | She smelled the flowers. |
| taste | The soup tastes salty. | He tasted the sauce. |
| sound | The explanation sounds clear. | The driver sounded the horn. |
Examples by pattern: nouns, adjectives, and phrases
Linking verbs are easiest to learn through patterns. Pattern one is subject + linking verb + noun. Examples include “David is my neighbor,” “Her goal became a business,” and “The winners were my classmates.” This pattern is common when you introduce people, define terms, or state professions. Pattern two is subject + linking verb + adjective. Examples include “The movie was boring,” “Your answer seems correct,” and “The streets remain empty.” This is the most productive pattern for everyday English because descriptions are everywhere.
Pattern three uses prepositional or other descriptive phrases after the linking verb: “The keys are on the table,” “The children are in the garden,” “Our manager is under pressure.” Some grammar books focus mainly on nouns and adjectives as complements, but ESL learners meet location and condition phrases constantly, especially with be. Pattern four includes participial adjectives: “The audience became excited,” “I feel exhausted,” “The instructions seem confusing.” These forms look like verbs, but in these sentences they function as adjectives describing the subject.
For accuracy, learners should notice agreement and tense. “She is ready” becomes “They are ready.” “He was upset yesterday” becomes “He has been upset all week.” In class, I often ask students to change only the tense while keeping the complement the same. That practice strengthens control of both the verb form and the linking function.
Frequent mistakes and how to correct them
The biggest mistake is using an adverb instead of an adjective after a linking verb. Say “The baby seems sleepy,” not “sleepily.” Another common problem is omitting be in the present tense, especially for learners whose first language allows zero copula. English requires the verb: “She is angry,” not “She angry.” A third issue is confusing present participles and past participles as adjectives. “I am bored” means I feel no interest; “I am boring” means other people find me uninteresting. Because linking verbs connect the subject to the adjective, the wrong adjective changes the entire meaning.
Learners also misuse sensory verbs by treating every instance as linking. “I smell gas” can mean I notice the odor, which is more like perception than pure linking. Context decides the grammar. Another subtle error appears with complement choice. “He became angrily” is wrong because become needs an adjective or noun complement: “He became angry” or “He became a leader.” On standardized tests such as TOEFL and IELTS, these distinctions often appear in sentence correction, speaking fluency, and writing accuracy.
How linking verbs connect to the wider grammar system
As a hub within miscellaneous grammar, linking verbs connect naturally to several related topics ESL learners should study next. First, adjectives: understanding comparative forms, adjective order, and participial adjectives improves accuracy after linking verbs. Second, subject and predicate structure: learners should know that a subject complement is different from a direct object. Third, verb types: distinguishing linking, action, auxiliary, and stative verbs helps with sentence analysis. Fourth, pronouns and case: formal complement pronouns appear after be in careful writing. Fifth, punctuation and style: concise sentences with strong complements usually read better than wordy clauses.
Linking verbs also support vocabulary growth. Instead of memorizing isolated adjectives, learners can build useful combinations such as “remain silent,” “feel confident,” “seem unlikely,” “become available,” and “stay organized.” Corpus-based tools such as the Cambridge Dictionary, Longman Dictionary of Contemporary English, and COCA can show which complements are common with specific verbs. For example, native usage strongly favors “become aware,” “grow stronger,” and “sound familiar.” Learning these combinations improves naturalness faster than studying single words alone.
Best practice for mastering linking verbs
The fastest way to improve is to combine noticing, pattern practice, and correction. When you read, highlight be, seem, become, remain, and sensory verbs, then identify the complement after each one. When you write, check every sentence with is, are, was, or were and ask whether the word after the verb correctly describes or identifies the subject. When you speak, practice short transformations: “The news shocked me” becomes “The news was shocking,” and “I tired after work” becomes “I feel tired after work.” I use this method because it turns grammar into a repeatable editing habit rather than a memorization task.
Linking verbs become much easier when you stop thinking of them as a long list and start seeing their job: they connect the subject to meaning. Remember the essential rules: use adjectives, nouns, or descriptive phrases after linking verbs; distinguish linking uses from action uses; and pay close attention to common verbs such as be, seem, become, look, feel, sound, smell, and taste.

Frequently Asked Questions
What is a linking verb, and how is it different from an action verb?
A linking verb connects the subject of a sentence to information that describes, renames, or identifies it. Instead of showing an action, it creates a relationship between the subject and a subject complement, such as an adjective, noun, or phrase. In simple terms, a linking verb tells us what someone or something is, seems, feels, or becomes. For example, in the sentence The soup is hot, the verb is does not show an action. It links the soup to the description hot.
This is the key difference from an action verb. An action verb shows what the subject does, such as run, write, eat, or sing. In The boy runs fast, the verb runs describes an action. In The boy is fast, the verb is links the subject to a quality. ESL learners often confuse these two patterns, especially when they are trying to build sentences quickly. That is why mistakes like She feeling tired happen. The adjective tired needs a linking verb, so the correct sentence is She is feeling tired or, more simply, She feels tired.
Understanding this difference helps learners make more natural sentences. When the word after the verb describes the subject rather than receiving an action, a linking verb is usually needed. This is one of the most useful grammar signals for improving accuracy in everyday English.
What are the most common linking verbs in English?
The most common linking verb is be, which appears in many forms: am, is, are, was, were, be, been, and being. These forms are extremely important for ESL learners because they appear in basic descriptions, introductions, locations, and states. Examples include I am ready, They are students, The weather was cold, and She is in the classroom. Because be is used so often, mastering it is essential for accurate speaking and writing.
Other common linking verbs include seem, become, feel, look, sound, appear, smell, taste, remain, stay, grow, and turn. These verbs often describe changes, impressions, or sensory experiences. For example, He seems tired, The sky became dark, The music sounds beautiful, and The milk smells bad. In these examples, the verbs do not show an action being done to an object. Instead, they connect the subject to a condition or description.
It is also helpful to remember that some verbs can be linking verbs in one sentence and action verbs in another. For example, look is a linking verb in You look happy, but an action verb in You looked at the painting. This is why learners should always check the role of the verb in the sentence, not just memorize a list. Context matters.
How can I tell whether a verb is being used as a linking verb?
A practical way to identify a linking verb is to look at what comes after it. If the word or phrase after the verb describes the subject or gives it a new name, the verb is probably linking. For example, in Maria is a teacher, the phrase a teacher renames Maria. In The children seem excited, the adjective excited describes the children. In both cases, the verb links the subject to more information about the subject.
Another useful test is to replace the verb with a form of be. If the sentence still makes sense with little or no change in meaning, the original verb is likely functioning as a linking verb. For example, The flowers smell lovely can become The flowers are lovely. The exact meaning changes slightly, but the sentence still connects the subject to a description. That suggests smell is acting as a linking verb here. However, in The dog smelled the food, you cannot replace smelled with was. This tells you that smelled is an action verb in that sentence.
ESL learners should also pay attention to whether there is a direct object. Linking verbs usually do not take direct objects because they are not transferring action to something. Compare She became angry with She kicked the ball. In the first sentence, angry describes she. In the second, the ball receives the action. This contrast makes it much easier to decide how the verb is being used.
Why do ESL learners often make mistakes with linking verbs?
Many ESL learners make mistakes with linking verbs because the pattern does not always match the structure of their first language. In some languages, a verb like be may be omitted in the present tense, or adjectives may work differently in sentence structure. As a result, learners may say She very kind instead of She is very kind, or They in happy instead of They are happy. These errors are very common because the learner understands the vocabulary but has not fully internalized the grammar link between subject and description.
Another reason is that linking verbs seem simple at first, especially the verb be, but they require several grammar decisions at the same time. A learner must choose the correct tense, the correct subject-verb agreement, and the correct complement. For example, I am tired, He is tired, and They were tired all use the same basic idea, but the verb changes depending on the subject and time. This can be challenging in real conversation, when students are focused on meaning and speed.
Some confusion also comes from verbs that can be either action verbs or linking verbs. A sentence like He looks nervous uses looks as a linking verb, while He looks at the map uses it as an action verb. Without clear examples and repeated practice, learners may not notice the difference. The good news is that these errors are very teachable. With exposure to patterns, correction, and sentence-building practice, most students improve quickly and start producing more natural English.
What are some easy rules and examples ESL learners can use to master linking verbs?
A very useful rule is this: when you want to describe the subject, you usually need a linking verb. If you want to say what someone is, how someone feels, what something seems like, or what something becomes, a linking verb is often the correct choice. For example, The room is quiet, My brother is a doctor, I feel sick, She seems worried, and The leaves turned yellow. In all of these sentences, the verb connects the subject to a description, identity, or condition.
Another easy rule is to watch for adjectives after the verb. Adjectives often follow linking verbs because they describe the subject. For example, The test was difficult, The baby looks sleepy, and Your idea sounds great. If you see an adjective after the verb and it describes the subject, that is a strong sign that you are dealing with a linking verb. Nouns can also follow linking verbs, especially after forms of be and become, as in She is my friend or He became the manager.
Finally, practice with common correction patterns can make a big difference. Compare incorrect and correct examples: She feeling tired becomes She is feeling tired. They happy becomes They are happy. The soup smell good becomes The soup smells good. He
