Fourth Grade English: Action, Linking, and Helping Verbs
Verbs are the engine of every complete thought you write or speak; without a verb, a collection of words cannot form a complete sentence. While many people think of verbs only as words that show physical motion like sprinting, climbing, or swimming, verbs actually perform three distinct and crucial functions in English. By learning to distinguish between action verbs, linking verbs, and helping verbs, you will understand the dynamic anatomy of sentences and become a far more versatile writer.
The Three Families of Verbs
Every verb in the English language belongs to one of three functional families based on what it accomplishes inside a clause.
+-----------------------------------------------------------------------+
| THE THREE VERB FAMILIES |
+-----------------------------------------------------------------------+
| [1] ACTION VERBS [2] LINKING VERBS [3] HELPING VERBS |
| Express physical Connect subject to Work with main|
| or mental actions a noun or adjective verb to create|
| - jump, think, run - is, seem, appear tense/mood |
| - was running |
+-----------------------------------------------------------------------+
Action Verbs: Physical and Mental Movement
Action verbs express what the subject does. They can describe visible physical movements or internal mental processes:
- Physical Action: "The eagle soared above the rocky cliffs."
- Mental Action: "Elena remembered the solution to the math problem."
Whether physical or mental, action verbs propel the sentence forward with energy.
Linking Verbs: Connecting State of Being
A linking verb does not show action. Instead, it acts like an equal sign (=) connecting the subject of the sentence to a word in the predicate that renames it (a predicate noun) or describes it (a predicate adjective).
- Renaming Subject: "Dr. Carver was a brilliant botanist." (Dr. Carver = botanist).
- Describing Subject: "The soup tasted delicious." (Soup = delicious).
Helping Verbs (Auxiliary Verbs): Supporting the Main Verb
Helping verbs assist the main verb in forming complex verb phrases that show exact time, continuation, or possibility. A helping verb always appears before the main verb.
- "The scientists are analyzing the satellite images." ("Are" is the helping verb; "analyzing" is the main verb).
- "We have completed our research project." ("Have" is the helping verb; "completed" is the main verb).
The Linking Verb Substitution Test
Certain verbs—such as smell, taste, look, feel, sound, appear, and remain—can function as action verbs in one sentence and linking verbs in another.
+-----------------------------------------------------------------------+
| THE EQUAL SIGN / "IS" TEST |
+-----------------------------------------------------------------------+
| Sentence A: "The chef smelled the fresh basil." |
| Test: "The chef IS the fresh basil?" NO! |
| Function: ACTION VERB (Chef is performing an action). |
| |
| Sentence B: "The soup smelled delicious." |
| Test: "The soup IS delicious?" YES! |
| Function: LINKING VERB (Smelled connects soup to quality).|
+-----------------------------------------------------------------------+
Applying the Test to Common Verbs
To determine whether a verb like "looked" or "felt" is action or linking, substitute a form of "to be" (is, am, are, was, were) in place of the verb:
- "The detective looked carefully at the clues." -> "The detective was carefully at the clues?" No! "Looked" is an action verb.
- "The detective looked confident." -> "The detective was confident." Yes! "Looked" is a linking verb connecting the subject to the adjective "confident."
The Helping Verb Roster (23 Auxiliaries)
Memorizing the twenty-three common helping verbs makes it effortless to spot multi-word verb phrases in reading and writing.
+-----------------------------------------------------------------+
| THE 23 COMMON HELPING VERBS |
+-----------------------------------------------------------------+
| Forms of Be | am, is, are, was, were, be, being, been |
| Forms of Have | have, has, had |
| Forms of Do | do, does, did |
| Modals | can, could, will, would, shall, should, |
| | may, might, must |
+-----------------------------------------------------------------+
Identifying Complete Verb Phrases
A complete verb phrase consists of one or more helping verbs plus one main verb:
- "She had been studying for three hours." (Helping: "had been"; Main: "studying").
- "The satellite will orbit the planet tomorrow." (Helping: "will"; Main: "orbit").
Note: Words like "not," "never," or adverbs like "quickly" are NOT verbs, even when placed between helping and main verbs: "They have not arrived yet." (Verb phrase is "have arrived"; "not" is an adverb).
Practice Exercises
Practice Questions
- Identify the verb in this sentence and label it as action or linking: "The ancient redwood trees grow tall in the valley."
- In the sentence, identify the complete verb phrase and separate the helping verb from the main verb: "The solar panels have generated electricity all morning."
- Use the substitution test to determine whether "felt" is an action or linking verb in this sentence: "The velvet fabric felt incredibly soft."
- Identify the predicate adjective linked to the subject in this sentence: "The night sky remained clear throughout the storm."
- Identify all the verbs in the verb phrase: "The astronauts will be traveling to Mars next decade."
Answer Key and Explanations
- "Grow" is an action verb describing physical growth (or can be interpreted as linking if meaning "become tall"; here "tall" describes their state).
- Complete verb phrase: "have generated." Helping verb: "have"; Main verb: "generated."
- Linking verb. Substitute "was": "The velvet fabric was incredibly soft." The substitution makes complete sense, confirming "felt" is linking.
- "Clear" is the predicate adjective linked to the subject "sky."
- Helping verbs: "will be"; Main verb: "traveling." Complete verb phrase: "will be traveling."
