be

beverb

American /bi/ British /biː/ The finite forms are often weak in connected speech: are can sound like er, was like wuz, were like wer, and am like uhm. The full, strong forms return for emphasis and at the end of a sentence, as in Yes, I am.
third-person singular is past tense was past participle been present participle being am, are; were

Be joins a subject to what it is, where it is, or how it is, and it also helps to form other tenses and the passive.

  1. describe or identifyused to join a subject to a word or phrase that names or describes it

    This is the ordinary linking use of be. The word after be says who or what the subject is (a doctor, my sister) or what it is like (tired, blue, ready). Be cannot be left out.

    Collocations

    phrase be able to do something, be about to do something, be supposed to do something, be worth doing

    For translators (sense 1)

    Grammar trap Be must appear between the subject and the word that describes it. Many languages leave it out and say the equivalent of she happy or he a teacher; English does not.
  2. place or timeused to give the place or time of someone or something

    Be links the subject to a phrase of place or time. The phrase usually begins with a preposition (in, on, at) or is a word like here or there.

    linking [L] verb + adverb or preposition [V + adv/prep]

  3. there isused after there to show that someone or something exists or happens

    In this pattern the real subject comes after be, and there fills the subject place: there is a problem, there are two ways. In careful English the verb agrees with the noun after it: there is one book, there are many books. There's before a plural noun is common in speech: there's two ways.

    Synonyms exist

    For translators (sense 3)

    Meaning across languages Some languages use their verb for have or a special word to say that something exists. English uses there plus be: there is, there are, there was. The there cannot be dropped.
  4. -ing tensesused with the -ing form of another verb to show that an action continues over a period of time

    This makes the continuous (progressive) tenses: am working, is raining, were waiting. It shows that the action is or was in progress rather than complete.

    verb + -ing form [V + -ing]

  5. passiveused with the past participle of another verb to show that the subject receives the action rather than does it

    This makes the passive: was built, is made, are sold. The person or thing that does the action is often left out or added with by: the letter was sent, the house was built by my grandfather.

    For translators (sense 5)

    Grammar trap English forms the passive with be plus the past participle. Languages that mark the passive on the verb itself, or that avoid it, need care here: was seen, is written, will be done.
  6. plan or orderused with to and another verb to talk about what will happen or must happen as a plan, an order, or something that has been agreed

    This use is a little formal and is common in news and instructions. It can give an order (you are to wait here), report a plan (they are to marry in spring), or say what is or was going to happen.

Usage

Be has more forms than any other English verb: am, is, are in the present, was, were in the past, been and being as participles. In speech and informal writing these join with the subject or with not: I'm, you're, it's, isn't, aren't, wasn't. In short answers the full form is used, not the short one: Are you tired? Yes, I am. (not Yes, I'm.)

Common mistakes

She very tired. She is very tired.
English needs a form of be between the subject and an adjective.
It has many people here. There are many people here.
To say that something exists, English uses there is or there are, not have or it.
I am agree with you. I agree with you.
Agree is a verb, not an adjective, so it is used without be.

For translators

Meaning across languages Some languages use different verbs for saying what something is and where it is, or have no such verb at all. English uses one verb, be, for identity, description, and place, and it cannot be left out.
Grammar trap Besides linking, be helps form the continuous tenses (is working) and the passive (was made), and the pattern be to do something. Learners should learn its irregular forms early: am, is, are, was, were, been.
