Summary
The verb “to be” is a core and irregular English verb used to express identity, states, feelings, location, and tense. This guide explains its main forms (am, is, are, was, were, been) and shows how they are used in everyday sentences, continuous tenses, and passive voice. It also highlights common mistakes and practical tips to help learners use “to be” correctly and confidently in real writing.
What Is the Verb “To Be”?
The verb “to be” is one of the most essential—and irregular—verbs in English. It expresses states, identities, conditions, feelings, and existence. Unlike regular verbs, which only change with tense endings, “to be” has multiple unique forms that vary depending on the tense and subject.
Common forms include:
● am, is, are (present)
● was, were (past)
● been, being (participles)
Because English uses “to be” to build core structures—such as passive voice, continuous tenses, and descriptions—mastering it is crucial to writing and speaking correctly.
In short:
● “am” → I
● “is” → he, she, it, singular nouns
● “are” → you, we, they, plural nouns
These irregular patterns make “to be” tricky for learners, so this guide breaks everything down step by step.
Understanding “to be” is important because it appears in nearly every type of English sentence. Whether you’re:
● describing a person or thing
● talking about states and feelings
● forming questions and negatives
● building continuous or passive sentences
…you will need the verb “to be.”
1. It supports major grammar structures
“To be” is necessary for:
● Present continuous: She is studying.
● Passive voice: The cake was made yesterday.

Without “to be,” these constructions cannot exist.

Mastering forms improves readability, professionalism, and fluency.
