Purpose
By the end of this lesson, you will be able to distinguish action verbs, linking verbs, and helping verbs, and understand how they combine in a sentence.Lesson Explanation
A verb expresses an action, occurrence, or state of being. English verbs fall into three functional categories that frequently combine within a single sentence. Action verbs describe something the subject does: “run, write, think, decide.” These are the most intuitive verb type and the largest category by far. Linking verbs connect the subject to a description or identity rather than describing an action — most commonly forms of “be” (am, is, are, was, were), plus verbs like “seem, become, appear, feel, look, taste, smell” when used descriptively: “She seems tired” (seems links “she” to the description “tired,” rather than describing an action she performs). Helping (auxiliary) verbs combine with a main verb to build tenses, questions, negatives, and passive constructions, rather than carrying meaning on their own. The three core helping verbs are “be,” “have,” and “do”: “She is running” (progressive tense), “She has finished” (perfect tense), “She does not agree” (negation) — this exact auxiliary system underlies every tense covered in Part 3. Modal helping verbs — “can, could, may, might, must, shall, should, will, would” — add meaning about possibility, permission, obligation, or certainty rather than tense alone, and are covered in full depth in Part 6, Lesson 3: “She should leave” (obligation/advice), “She might leave” (possibility).Practice Questions
