The verb to be is the foundation of the English language. Unlike regular verbs that follow a predictable pattern, “to be” is highly irregular—meaning it changes shape entirely depending on the tense, the person, and whether the subject is singular or plural.
Whether you are a student mastering grammar or a writer tightening your prose, understanding these linking verbs is the first step toward clear, professional communication.
What are be verbs?
In English, the verb “to be” functions as a linking verb, connecting the subject of a sentence to a description, a state of being, or a location. It does not always show action; instead, it tells us what something is.
The primary functions of be verbs
- Linking subjects to descriptions: “I am hungry” or “The sunset is beautiful.”
- Indicating location: “The keys are on the counter.”
- Forming continuous tenses: “They are studying for the exam.”
- Creating passive voice: “The letter was sent yesterday.”
- Existential statements: “There is a solution to this problem.”

Mastering the complex tenses of to be
Once you move past the basics, “to be” acts as an auxiliary verb (a helping verb) to build continuous and perfect tenses.
The continuous tenses
Continuous tenses describe ongoing actions. In these cases, we use a form of “be” combined with a present participle (the -ing form).
- Present continuous: “I am being honest with you.”
- Past continuous: “They were being very helpful during the move.”
- Future continuous: “This time tomorrow, we will be flying to London.”
If you are a visual learner, using visual grammar flip charts or dry erase tabletop easels can help you keep these complex tense structures in view while you write.
The perfect tenses
The perfect tenses use the past participle form: been.
- Present perfect: “She has been a teacher for ten years.”
- Past perfect: “I had been asleep for an hour when the phone rang.”
- Future perfect: “By next month, they will have been married for a decade.”
The perfect continuous tenses
These tenses emphasize how long an action has been going on.
- Present perfect continuous: “I have been working on this project since Monday.”
- Past perfect continuous: “He had been waiting for two hours before the bus arrived.”
- Future perfect continuous: “In June, I will have been living in Chicago for five years.”
