🔤 The Verb "To Be"
The most important and irregular verb in English — am, is, are, was, were
Present Forms
"To be" is the most irregular verb in English — it has three present forms where most verbs have only two. You must memorize each form. The good news: contractions (short forms) are used constantly in speech and informal writing.
| Subject | Full Form | Contraction | Example |
|---|---|---|---|
| I | am | I'm | I'm a student. |
| you | are | you're | You're right. |
| he | is | he's | He's from Berlin. |
| she | is | she's | She's a doctor. |
| it | is | it's | It's cold today. |
| we | are | we're | We're ready. |
| they | are | they're | They're coming. |
Negatives & Questions
Unlike most English verbs, "to be" doesn't need "do/does" to form negatives or questions. Just add "not" for negatives, or invert the subject and verb for questions.
| Type | Structure | Example |
|---|---|---|
| Negative (full) | subject + be + not | She is not ready. |
| Negative (contraction 1) | subject + be + n't | She isn't ready. |
| Negative (contraction 2) | subject's + not | She's not ready. |
| Yes/No question | be + subject | Is she ready? |
| Wh- question | Wh- + be + subject | Where is she? |
| Negative question | be + n't + subject | Isn't she ready? |
Past Forms: Was & Were
"To be" has two past forms: "was" for I/he/she/it (singular) and "were" for you/we/they (plural). This is simpler than the present — just two forms to remember.
| Subject | Past Form | Example |
|---|---|---|
| I | was | I was tired yesterday. |
| you | were | You were late. |
| he/she/it | was | She was happy. |
| we | were | We were at the park. |
| they | were | They were busy. |
"To Be" as an Auxiliary Verb
"To be" also serves as a helper (auxiliary) verb to build other tenses and the passive voice. You'll encounter it constantly:
| Construction | Example | Tense/Voice |
|---|---|---|
| am/is/are + -ing | I am learning English. | Present Continuous |
| was/were + -ing | She was reading a book. | Past Continuous |
| am/is/are + past participle | The door is locked. | Present Passive |
| was/were + past participle | The house was built in 1900. | Past Passive |
| am/is/are + going to | We're going to travel. | Future (plans) |
Common Mistakes for German & Russian Speakers
Both German and Russian speakers make predictable errors with "to be." Here are the most important ones to avoid:
| Mistake | Why It Happens | Correct Form |
|---|---|---|
| "I have 25 years" | Russian "Мне 25 лет" uses a dative construction; some languages use "have" for age | "I am 25 years old" |
| "I am agree" | Confusing adjective and verb patterns | "I agree" (agree is a verb) |
| "Is raining" | Russian/German can omit the subject | "It is raining" (English needs "it") |
| "He is come from Germany" | Mixing up "be" with other verbs | "He comes from Germany" |
| "I am not have a car" | Using "be" where "do" is needed | "I don't have a car" |
