A helping verb, also known as an auxiliary verb, is a verb that accompanies the main verb in a sentence and provides additional information about the main verb’s tense, mood, or voice.

Some common helping verbs include:

• Be (am, is, are, was, were, etc.)
• Have (has, had)
• Do (does, did)
• Will
• Would
• Should
• Could
• May
• Might
• Must

For example:

• “She is running to the store.” (The helping verb “is” indicates the present progressive tense)

• “He has finished his homework.” (The helping verb “has” indicates the present perfect tense)

• “They will attend the concert tonight.” (The helping verb “will” indicates the future tense)

Helping verbs work together with the main verb to create a complete verb phrase that provides more detailed information about the action being described. They play an important grammatical role in forming complex verb tenses, voices, and moods in sentences.
