Helping verbs, also known as auxiliary verbs, are essential for forming verb tenses, voices, moods, and questions in English. They work alongside main verbs to add detail, indicate time, express conditions, or convey emphasis.
What Is a Helping English Verb?
A helping verb is a verb that supports a main verb in a sentence to form a verb phrase. It helps indicate aspects such as tense, voice, mood, or possibility.
Common Helping Verbs:
Am, is, are, was, were, be, being, been, have, has, had, do, does, did, can, could, may, might, shall, should, will, would, must, ought to.
Example:
- Main Verb: Run
- Helping Verb + Main Verb: She is running.
Why Helping Verbs Matter?
Helping verbs:
- Show time and tense (e.g., has eaten, will go)
- Express continuous actions (e.g., is studying)
- Form the passive voice (e.g., was written)
- Add emphasis (e.g., I do know the answer.)
- Indicate possibility, necessity, or ability using modal verbs (e.g., must study, can swim)
